Geogrids are being used in transportation application often in embankment construction due to their ease of construction and economy compared to traditional methods. Utilizing polymer materials in order to improve the performance of road structure is based on two factors, decreasing deformation and increasing bearing capacity. In this study geogrids were tested to check the ability of increasing load carrying capacity for highway projects. The purpose of this research work was to find a relation between the loading of the geogrid, the thickness of the aggregate layer and its bearing capacity. This would normally lead to an investigation on the lateral restrain behavior of a geogrid. According to the results obtained from soil mechanics laboratory, it could be demonstrated that by utilizing geogrids , the probability of occurring rutting decreases 30% and the bearing capacity of soil increase 40 % respectively.DOI: http://dx.doi.org/10.3126/njst.v15i1.12020  Nepal Journal of Science and TechnologyVol. 15, No.1 (2014) 77-80

An experiment of sixteen frame column underpinning joints of frame structure moving was introduced, the experiment sample failure phenomena and failure type was obtained. The type was like “deep beam” failure type-“tension bar arch”, and the last failure place occurred on the interface of column and beam. Then, the underpinning joint stress mechanism and failure mode was determined based on the experiment’s conclusion. In addition, the failure course of joint was divided two stages which were before and after interface punching slip by theoretical analysis, for the stage before interface punching slip a space “tension-bar-arch” mechanical model was presented for the underpinning joint, then theoretical bearing capacity equation for this underpinning joint were obtained. At the same time, for the stage of interface after punching slip, the theory of interface shear was put into the analysis of joint, then interface bearing capacity equation was obtained for this stage. At last the height equation was obtained by the analysis of the stage of after interface slip.

  The present investigation is based on the development of a study that determines the soil bearing capacity as a geotechnical parameter, applying the DCP penetration dynamic cone test, in the adjacent areas to the Faculty of Mathematical, Physical and Chemical Sciences. The values obtained from the DCP index correlated with experimental formulas allowed obtaining the soil bearing capacity, also establishing parameters such as grain size, humidity, compaction, Atterberg limits, resilient module regulated by the AASTHO, subsequently characterizing the different samples from the results obtained in the soil mechanics laboratory. When defining the results obtained in the investigation, parameters were determined that detail the composition of the soil at the study site, in which a CBR was obtained categorizing it as “poor to regulate” in terms of the quality of the subgrade. Furthermore, the texture of the material was classified as silt soils from low to high plasticity. Thus, it is proposed to use the information obtained in the investigation for the projection of future civil works that contribute to the integral development of this alma mater.   Index Terms- California Support Value (CBR), Dynamic Standard Penetration Cone (DCP), Resilient Module, Test, Subgrade, Pavement.

The purpose of this paper is to develop a method for predicting the creep settlement and the bearing capacity of frozen soils under deep circular loads. The theory uses experimentally determined creep parameters of frozen soil and is intended to be applicable to the design of deep circular footings and screw anchors embedded in permafrost soils. On the basis of available experimental evidence, it was concluded that a mathematical model different from that usual in soil mechanics should be used in solving the time-dependent bearing capacity problem of such footings. The solution proposed in the paper was obtained by using the mathematical model of an expanding spherical cavity in a nonlinear viscoelastic-plastic medium with time, temperature, and normal pressure dependent strength properties. For a given footing or anchor, the theory furnishes either isochronous load-displacement curves, or load-creep rate curves, or a time-dependent bearing capacity for which formulas and graphs of nonlinear elastic-plastic bearing capacity factors are supplied.The theoretical predictability of creep rates and ultimate failure loads was checked against the results of screw anchor tests carried out by the Division of Building Research, N.R.C.C., at a permafrost site in Thompson, Manitoba. It was found that the use in the theory of the creep parameters determined by creep-pressuremeter tests performed at the site, resulted in a satisfactory agreement between the predicted and the observed behavior.
