一个用于边坡稳定分析的通用条分法

GENERALIZED LIMIT EQUILIBRIUM METHOD FOR SLOPE STABILITYANALYSIS

介绍了通用条分法的基本方程。与经典公式的不同在于,它直接将条间力合力的大小和方向作为未知数,通过定义不同的条间力倾角函数,可以方便地模拟各种严格条分法,如Spencer法、Morgenstern-Price法以及基于力平衡的简化法,如不平衡推力法、陆军工程师团法、罗厄法等。方程的求解采用了RapidSolver法,算例分析表明,通用条分法GLE具有较高的数值精度和实用价值,且方程形式简单、易于编程。

The basic equations of generalized limit equilibrium method (GLE) are introduced, in which the difference from the classical methods is that the value and direction of interslice force are regarded as unknowns. The Rapid Solver is adopted to solve equations. Through defined function of interslice force angles, GLE can emulate rigorous methods such as Spencer and Morgenstern-Price methods, as well as other simplified methods satisfying force equilibrium, such as the unbalance thrust force method, Corps of Engineers, and Lowe-Karafiath method and etc. The results show that GLE is a practical method with high precision and has the advantages of simple formulation to program easily.
