It is common that geotechnical samples are delimited according to the natural geological origin and period. The necessity of dispersion of geotechnical sampling probability distribution, and the degree of diversity is relative to partitioned range of the base layer are expounded. Based on the analys...
Performance Study on Slope Slip Surface Generation by Spline Function
Li Liang, Wang Qiusheng
2008, 22(3): 113-118.
[Abstract](44) [PDF 480KB](7)
Abstract:
The two-dimensional slip surfaces are usually generated by connecting a series of nodal points, of which the coordinates are optimized to locate the critical slip surface. The more the number of nodal points is, the more the number of optimization variables. Based on several nodal points, the Spline...
Stability Analysis for Soil-Rock Composite Slope

[Abstract](69) [PDF 189KB](11)
Abstract:
Based on the FLAC2D finite difference software, strength reduction theory has been used to gained the stability factor of the 48 soil slopes under the different conditions. Grey Correlation Analysis Method of the Grey System Theory is employed to analyze the sensitivities of factor influencing slope...
Secondary Inner Force Analysis of Column-Anchor Retaining Structure with Concrete Creep
Wang Houyu, Liu Zhijie, Yan Zhixin
2008, 22(3): 127-130.
[Abstract](46) [PDF 361KB](7)
Abstract:
A practical method of secondary inner force analysis is presented for column-anchor retaining structure considering concrete creep based on concrete aging creep theory and equivalent elastic modulus. The results of secondary inner force of a detail retaining structure are also presented and discusse...
Model Test Research for Eccentric Prestressed Anchor Rope Anti-slide Pile
Jin Bo, Cheng Fangfang, Chen Ningning
2008, 22(3): 131-135,138.
[Abstract](59) [PDF 1176KB](7)
Abstract:
Eccentric prestressed anchor rope anti-slide pile is also called eccentric pile. It is a new type anti-slide pile structure. It is first advanced and applied for landslide correction of Huang Yah expressway(k224). Based on the result of the large model failure test of eccentric pile in laboratory te...
Analysis of Bearing Capacity of Ram-compacted Piles With the Bearing Base in Chengdu clay
