| 摘 要： | 常规二维滑坡推力计算没有考虑其横向变化,导致设计过于保守,三维推力计算方法的提出则能体现滑坡推力的空间分布,解决二维存在的问题.本文在三维极限平衡法统一模型的基础上,建立了求解三维滑坡推力的统一公式.利用实例,通过二维推力计算与三维计算结果的对比分析,获得三维推力的横向分布函数,有效反映出三维滑坡推力的空间分布状态,所...

| Abstract: | The common two-dimensional(2D)methods for the driving forces of landslides don't consider the lateral variation and confinements,which can make the stabilization design un-precisely.Three-dimensional(3D)method can reflect the spatial distribution of the driving force of landslide.So it can resolve the problem of 2D methods.This paper provides a general formula for calculating the driving force of 3D landslide.It is based on the method of the general form of 3D equilibrium proposed by the authors.The paper p... |
