Study of seepage and stability of foundation pit under continuous rainy conditions Zengrong Liu1,a, Haibing Qiu1, b and MingqingPeng1,c 1 Civil Engineering Institute, XI’an Architecture and Technology University, Xi’an, Shanxi, 710055, China alzr@nwpu.edu.cn, b532357815@qq.com, c1002461384@qq.com Keywords:Rainstorm, Continuous rainy, MIDAS, Slope stability.
The basic principal of strength reduction method of soil is shear strength parameters and value simultaneously divided by a reduction factor R until the destruction of the slope reaches a critical state .The reduction factor R is the safety factor ,namelyFs ,whose formulations are: (5) Case Analysis Engineering situation .This paper takes a deep foundation pit construction as an example .The deep foundation pit ,with a excavation depth of 17meters ,is locate in Xi’an Hi-tech Development Zone ,for which slope pile and prestressed anchor are adopted to support the side slope .According to the survey report ,the main soil physical parameters are as follows : Table 1The main soil physical parameters Formation Bulk density Saturated unit weight Cohesion Friction angle Compression modulus (kN/m3) (kN/m3) (kN/m2) (°) (Mpa) Losess-like soil 16.4 16.5 14.1 0.925 9.21 Loess 16.5 16.1 14.2 0.907 9.38 Paleosof 17.4 19.9 14.5 0.867 9.32 Silty clay 18.1 23.6 14.6 0.851 8.01 The
Conclusion In fact ,the geotechnical problems are very complex in engineering ,especially the percolation and stability of unsaturated soil slope .The calculated results still need to more monitoring date to validate due to time and other objective constrains ,although the author has studied the numerical analysis according to the actual project situation .
In the paper ,it mainly explores the stability and the retaining structure’s variation regularity of the internal forces about deep foundation of pile-anchor retaining under rainfall conditions .And it would provide certain theory and experience for pits in practical engineering under continuous rainfall conditions when we comes across the problems of slope stability .
