Then, with the limit equilibrium method and three-dimensional finite element method, the stability of slopes in natural condition and that after excavation is calculated and simulated.
Compared with the displacement criterion of characteristic points,the entirely run-through criterion of plastic zone is more rational for its theoretical coherence to the theory of limit equilibrium and its easy use in application.
Then, with the limit equilibrium method and three-dimensional finite element method, the stability of slopes in natural condition and that after excavation is calculated and simulated.
In this paper rigid block partitioned limit equilibrium method is used to analyse the multiple rigid block model formed by faults f_5 and f_2 in Jinping Dam left abutment.
When the dam will be up to 80m height (+600m), the stable coefficient in the flood condition will be equal to 1.147 which is just smaller than the code’s (1.15), the dam will in the limit equilibrium state.
Based on the limit equilibrium of the soils′ thin-layer elements in the back of retaining wall,calculation formula of the active earth pressure for the clayey soils is suggested.
Based on a summary of the achievements of slope stability analysis, it introduced the application of limit equilibrium method and finite element method for slope stability analysis, esp.
with the dialing dam pilled on, up to + 1350m, its stable coefficient is 1.145 which is slightly smaller than code's value 1.15, and the dam will in the limit equilibrium state;
This article presents a brief description of the protective sealing wall method employed by a certain mine while driving through a fractured zone about 10 meters long.In the execution of this working method, correct estimation of the frontal ground pressure on the wall is of great significance. In this article, on the basis of the limit equilibrium theory of loosened medium [1], the problem has been greatly simplified, and on the assump-tion that pressure of broken rocks at boundary CDE of the #...
The conventional limit equilibrium method for the calculation of the stability of a dam is the "Wedge Analysis" method, which is an analysis based on the assumption of a rigid base rock. In a series of gypsum models tests it has been observed that near the toe of the dam a plastic zone appeares, while the dam slides along a thin, soft layer inclined downstream. This paper presents a formula based on plasticity theory to estimate the safety factor of an isotropic base rock or a layered base rock ...
The stability analysis of a dam on layered rock foundation is one of the important problems encountered in dam construction. But now, the methods available for analysis are far from being complete. Among the various methods, the limit equilibrium method for the calculation of the stability of a dam is applied more widely. The finite element method is also used increasingly. Moreover, the model test made of brittle material gives us some supplementary information. This paper describes and discuss...
