Viewpoints on Statistical Inference for Geotechnical Sampling
Li Zhengyi
2008, 22(3): 109-112,122.
Abstract:
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:
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
Zhang Lianhua, Tang Lingxiang, Luo Kang
2008, 22(3): 119-122.
Abstract:
For soil-rock commixture, there is no standard model of design calculation in existing criterions. Based on the investigating data, the circular sliding method is adopted to search the most dangerous potential slide surface in the intenseweathered layer and the soil. And the most dangerous potential...
Sensibility Analysis of Soil Slope Stability on Mechanical and Geometrical Parameter
Liu Lipeng, Yu Hongjie, Chen Qi
2008, 22(3): 123-126.
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:
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:
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...

2008, 22(3): 136-138.
Abstract:
The bearing property of ram-compacted piles with the bearing base in Chengdu clay is discussed and the bearing capacity is estimated based on the Specification for Design of Ram-compacted Piles With Bearing Base(JGJ 135-2007)and the loading test result of the first engineering example of ram-compact...
Computation Method of the Single Pile Bearing Capcity of Post-grouting Spinning Drill Pile
Liang Jinguo
2008, 22(3): 139-144.
Abstract:
Based on the in-site measurement results of the post-grouting spinning drill pile, the engineering properties, load transferring law and side-friction distribution law of pile are analyzed. The development degree of side-friction of the pile, which subjected vertically loads, decays with the buried ...
