不平衡推力法在滑坡治理中的应用研究

Application of Unbalanced Thrust Transfer Coefficient Method in Landslide

运用不平衡推力法,通过判别现场划分工程等级,取土实验从而确定各个工况下的C、及不同工况安全系数的设定,以四川某滑坡治理为例,在不同工况下进行滑坡稳定性分析计算,结果与实际调查一致。并与隐式法比较,说明不平衡推力法是简便、有效的,在工程实践中具有广泛的应用性。

Unbalanced thrust method is known as transfer coefficient method or residual thrust method. It has a clear concept, simple calculation can be directly used to estimate the characteristics of landslide thrust, but there are also problems such as poor accuracy. In this paper, unbalanced thrust method is employed, which is divided by evaluating the project site level, and soil test is used to determine the various conditions of the C, Ф and different working conditions to set the safety factor, a landslide in Siehuan landslide stability in different conditions is analyzed and calculated, the results are consistent with the actual survey. Compared with the implicit method, the unbalanced thrust method is simple and effective, and has a wide range of applications in engineering practice.
