This study was conducted at the Bhasu Bhir of Kailali district in the Far-western Province, along the Khanidanda-Sahajpur road section of Bhimdatta pant highway. The main objective of this study is to identify the potential slope failure area and assess the major control factors along the road section. To accomplish the objective, the dip amount and dip direction of major discontinuity was measured in the field along with hill slope and hill slope direction. The data of 40 locations were analyzed by using stereographic projection method. The result was obtained by using Dips 6.0 software. The major slope failures obtained on the area were wedge failure and plane failure. The hill slope geometry, joint status and rock geometry are found major controlling factors for the slope failure in the study area.

Analytical Results

The research aimed to study 24 rock slope surfaces along the road around Hon Lon Island, Kien Hai district, Kien Giang province, Vietnam. The analytical results have determined slope failure, wedge failure, and toppling, which occurred on almost slope surface and the average percentage of plane failure is the largest. The average percent of plane failure is 19.23%, the wedge failure is 15.35%, and the toppling fault is 6.73%. Besides, the analytical results have also identified the slope surfaces which can be the key blocks: ND-13, 18, 23, 25, 34, 37, 45, 51, 62, 63. The other analytical results show that the existence of key blocks at the rock slope surfaces in the N-S direction, dip to E at the survey locations: ND-13, 23, 63 and dip to W at the survey locations: ND-37, 45; in the NE-SW direction, dip to SE at the survey locations: ND-15, 62 and dip to NW at the survey locations: ND-18, 34; in the NW-SE direction, dip to SW at the survey location ND-51. These results have important significance to support for protecting slope surface safety.

Joint Pattern

The present study assesses the slope stability at the most significant Baglihar Dam for slope failure and landslides occurrences. The study comprises of twelve sites which were selected for detailed geotechnical investigation for assessment of potential slope failures using basic Rock Mass Rating (RMRb), Slope Mass Rating (SMR) and kinematic analysis techniques. The results show that even though the rocks are of fair quality but other factors including joint pattern and density caused by tectonic and anthropogenic activities have rendered three sites completely unstable, 8 sites are unstable and one site is stable. Moreover Nine sites are susceptible to wedge failure, six to topple and two to plane failure. The RMRb value varies from 45 to 55 and SMR value varies from 11 to 44. The thorough results and interpretation of work done is presented in this paper.

The Hill

A hill with a lattice transmission tower presents complex wind field characteristics. The commonly used computational fluid dynamics (CFD) simulations are difficult to analyze the wind resistance and dynamic responses of the transmission tower due to structural complexity. In this study, wind tunnel tests and numerical simulations are conducted to analyze the wind field of the hill and the dynamic responses of the transmission tower built on it. The hill models with different slopes are investigated by wind tunnel tests to measure the wind field characteristics, such as mean speed and turbulence intensity. The study shows that the existence of a transmission tower reduces the wind speed on the leeward slope significantly but has little effect on the windward slope. To study the dynamic behavior of the transmission tower, a hybrid analysis procedure is used by introducing the measured experimental wind information to the finite element tower model established using ANSYS. The effects of hill slope on the maximum displacement response of the tower are studied. The results show that the maximum value of the response is the largest when the hill slope is 25° compared to those when hill slope is 15° and 35°. The results extend the knowledge concerning wind tunnel tests on hills of different terrain and provide a comprehensive understanding of the interactive effects between the hill and existing transmission tower regarding to the wind field characteristics and structural dynamic responses.

The rocks exposed along the road between Linstead and Guy's Hill, Jamaica, were described by Dr. C. T. Trechmann in this magazine in 1936 (pp. 259–260). The chief object of his account was to prove that the igneous rocks there were intrusions later than the associated Cretaceous and Tertiary limestones, which, according to him, had been metamorphosed into hornfelses, some of which, he stated later (1937, p. 561), he knew to have an “igneous” appearance under the microscope, “which tends to support my contention that in Jamaica we have sedimentaries altered in situ into rocks that would ordinarily be classified as igneous.” Dissent from his descriptions and interpretations was expressed by C. A. M. (Matley, 1937, pp. 501–3), the criticisms being mainly based on an examination of Trechmann's own microscope slides by F. R. A visit to Jamaica by C. A. M. in 1939 allowed him to study this road and to collect a suite of rocks for petrological examination. The results show that Trechmann's interpretation cannot be sustained. There is no granodiorite or other plutonic rock present, no metamorphism hornfelsing the sedimentary rocks, and no igneous intrusions into the Tertiary limestones.

I derive the materials of the present paper from some memoranda which I find amongst my archaeological notes and which relate to certain explorations to which I was not a party, made so long ago as 1887. I have thought that the particulars then obtained may be deemed sufficiently interesting to deserve a record in the history of Trojan archaeological discovery.The subject is one of the four small tumuli dotted about and near the hill of Balli-Dagh, the crest of which according to the now exploded theory of Le Chevalier (1785) was supposed to represent the Pergamos of Troy. In a memoir contributed to the Journal of the Archaeological Institute of 1864, I proved that the site in question was no other than that of the ancient city of Gergis. In the same paper I gave an account of the results of the excavation of one of the group of three tumuli on Balli-Dagh, the so-named Tomb of Priam. The other two, namely Le Chevalier's Tomb of Hector, and an unnamed hillock, were excavated respectively by Sir John Lubbock (about 1878) and Dr. Schliemann (1882) without result. The present relates to the fourth mound on the road between the villages of Bournarbashi and Arablar (as shown in the published maps), which goes by the name of Choban Tepeh (Shepherd's hillock) and the Tomb of Paris, according to Rancklin (1799).

В статье проанализированы трудности в процессе строительства автомобильной дороги от Братского моста через Енисей в сторону Абакана, связанные с отсутствием учета на стадии проектирования осложнившихся гидрогеологических условий, влияющих на опускание моста и дороги. Оползневые процессы, созданные искусственно при сооружении выемки дна автомобильной дороги от Братского моста более 40 лет развиваются на участке дороги Абакан-Подсинее перед железным и автодорожным мостом через Енисей. Как и в первом случае на стадии проектирования не выполнены гидро-геологические исследования. The article analyzes the difficulties in the process of construction of the highway from the Bratsk bridge over the Yenisei river to Abakan, associated with not taking into account the complicated hydrogeological conditions at the design stage, associated with the lowering of the bridge and road. Landslide processes created artificially during the construction of the dredging of the road bottom from the Bratsk bridge have been developing for more than 40 years on the Abakan-Podsinee road section in front of the railway and road bridge over the Yenisei. As in the first case, hydrogeological studies were not performed at the design stage.

The City

On the 3rd of Ramazán, I left Ramlah, and went to a village called Khátún, and from thence to another, which they styled Kariatu-l-'Anab (Grape hamlet). On the road I observed plenty of wild rue growing spontaneously on hill and dale. I also noticed at this village a very delightful spring of water gushing out of a rock, where they had constructed reservoirs, and built edifices. From thence I proceeded up some rising ground, under the impression that I was ascending a hill, and that on going down the other side the city would lie before me. After I had climbed the ascent however for a short way, a vast wilderness lay in my front, partly stony, and partly showing merely the bare earth. At the summit of the hill stands the city of the “Baitu-l-Mukaddas” (Sacred Tabernacle, i.e. Jerusalem), between which and Tarábulis, whichis on the coast, are 56 parasangs, and from Balkh to Jerusalem 876.
