Mechanics, Chinese Academy of Sciences), Wuhan 430071, China)Abstract:The core of strength reduction method (SRM) involves finding a critical strength curve that happens to make the slope globally fail... A and B with the slope angles of 63° and 34° respectively, were given to verify the method presented. It is found that, for these two slopes, the FOSs from original strength reduction method......
stabilized earth (MSE) structures can be analyzed either using limit equilibrium method (LEM) or strength reduction method (SRM) in finite element/difference method. In LEM, the strengths... the factor of safety of the MSE structures. To overcome this, an iteration method is proposed to consider the strength reduction of the reinforcements in SRM. The method is demonstrated by using PLAXIS......
Slope analysis based on local strength reduction method and variable-modulus elasto-plastic modelYANG Guang-hua(杨光华)1, 2, 3, 4 , ZHONG Zhi-hui(钟志辉)1, FU Xu-dong(傅旭东)1, ZHANG Yu-cheng(张玉成)2, 3, WEN..., Guangzhou 510640, China)Abstract:Employing an ideal elasto-plastic model, the typically used strength reduction method reduced the strength of all soil elements of a slope. Therefore, this method was called......

For the reasons mentioned above, by using upper bound limit analysis and strength reduction method, the main point of this work is to get the upper bound solution of safety factor......
equilibrium method or the strength reduction technique, is smaller with the changeable cohesion c(t). But the changing rate calculated by couple analysis is dynamic because of its rheological properties...J. Cent. South Univ. Technol.

Introduction The strength reduction method was first proposed by BISHOP [1] in 1955. The core of this method is the factor of safety which is defined as the ratio of the available shear strength of the soil... for the application of the strength reduction method in geotechnical stability analysis. Firstly, the computational process of this method is simple and the mechanical meaning is clear. Furthermore, the factor......

This method can simulate... region by the traditional finite element method. As a result, strength reduction theory begins to apply to tunnel stability analysis. The aforementioned research for tunnel stability analysis......
