关于土坡滑动的稳定性分析,已有的计算方法都将土坡滑动当作二向应力问题来处理,未考虑上坡滑动速度的影响,这是不全面的。关于三向滑坡问题的研究较少,阿里斯朵斯基的论文分析了二向应力解与三向应力解的误差,提出了三向问题的两种典型滑坡来研究,其第一种典型在实际调查与理论上都不符合滑坡的发展过程;第二种典型也未从本质上分析为何引起滑坡,没有阐明其应力状态和发展过程。
Regarding the stability analysis of slope sliding, the existing calculation method treats the slope sliding as a biaxial stress problem without considering the influence of the uphill sliding speed. This is incomplete. There are few studies on the three-way landslide problem. Alysdowski’s paper analyzes the errors between biaxial stress solutions and triaxial stress solutions, and proposes two typical landslides with three-way problems. The first one is typical. Both the actual investigation and the theory are not in line with the development process of the landslide; the second typical model has not analyzed the nature of the landslide, and has not elucidated its stress state and development process.
