Over Time

The behavior of soil either as a building material or as a load receiver is particularly important and presents a paramount significance in both infrastructure and building construction. Geotechnical engineering has shown a rapid development over the last fifty years and holds a prominent position in all scientific fields of engineers. This paper mainly aims at the historical background along with the progress made on Soil Engineering as an important branch of Surveyors, Civil and Mining Engineers, where, through an important citation of technical works and constructions over time, may be considered as a significant tool for teaching and education of students

Side slop losing stability is one of the main factors which greatly influences freeway expedite construction, especially after side slop losing stability the determination of rock and soil mechanics parameter may take a long time. Inversion method to analyze slope stability can preferably solve the problem. During the treatment of the ecological freeway landslide, we can not obtain important Parameters due to great disparity of sample Parameters of landslide. However, using inversion method to get cohesion and internal friction Angle, and anglicizing its sensitivity during calculation of stability can identify reliable Parameters. According to slope stability calculus, the ecological reinforcement design scheme come into effect.

According to the seismic analysis of the soil mechanics for the major and complex geotechnical engineering projects such as highway, high-speed railway, subway, dams and so on, there is acute lack testing instrument considering the level earthquake load and the vertical earthquake load. In order to resolve this problem a new design plan is putted forward in this paper, which can generate bidirectional exciting force with designed amplitude ratio, phase and waveform. The radial exciting subsystem (water pressure) and the axial exciting subsystem (force) are both built by the hydraulic servo systems. The two subsystems have excellent dynamic response characteristics. Several key technical issues existing in bidirectional exciting control have been discussed in detail such as: (1) high-precision unconventional bidirectional exciting control strategy; (2) decoupling control methods in the bidirectional exciting process; (3) real-time compensation by using digital image technology. The instrument will provide advanced test conditions for the complex geotechnical engineering.

Industry Sectors

The geotechnical construction industry is a major component of the overall construction sector and is strategically important in infrastructure development (transportation, flood and landslide protection, building foundations, waste disposal). Although industry and research in the overall construction sector have been investing significantly in recent years to produce innovative low-carbon technologies, little innovation has been created in geotechnical construction industry, which is lagging behind other construction industry sectors. This paper discusses the interplay between low-carbon geotechnical engineering and unsaturated soil mechanics based on the research carried out within the project TERRE (Marie Skłodowska-Curie Innovative Training Networks funded by the European Commission, 2015-2019,H2020-MSCA-ITN-2015-675762).

Geotechnical engineering embraces soil mechanics, rock mechanics, and engineering geology. In practice it employs a wide variety of techniques ranging from site mapping and characterization to advanced theoretical analysis and performance monitoring. This paper draws on the development of the Alberta oil sands as a case study to illustrate the breadth of application of geotechnical engineering in large-scale resource developments.A description of the resource base and common extractive procedures used in the Alberta oil sands is given. The geological setting and geotechnical characterization of the Athabasca deposit are summarized. Detailed discussions are presented on geotechnical contributions to surface mining and slope stability, waste handling and tailings dam construction, and in situ recovery processes. The substantial opportunities for geotechnical engineering to contribute to both safe and economical operations in the extractive industries are emphasized. Key words: oil sands, mining, slope stability, monitoring, dredging, shear strength, tailings dam, overburden, liquefaction, pore pressures, geotechnical engineering.
