提要:本文介绍在不同活动面上具有三向滑动体的活动稳定,活动体由诸多垂直薄片组成,同时每片假定是在极限平衡状态,作用在每片的侧面及滑动面上各自的力系经过验算,并计算其安全系数,三向平衡方程式组通常用作求出未知力、力臂、及安全系数。必要的数字计算以检验其物理意义,是这一分析的组成部分。这一方法适用在平面变形不能应用时,当考虑地震烈度时本方法仍能应用,这一方法曾用数字计算机进行过,并介绍一些实例。
Abstract: This paper describes the three-way sliding body’s activity stability on different moving surfaces. The moving body consists of many vertical slices. Each piece is assumed to be in the limit equilibrium state. Each force acts on the sides and slide surfaces of each piece. After checking and calculating the safety factor, the three-way equilibrium equation group is usually used to find the unknown force, arm, and safety factor. The necessary numerical calculation to test its physical significance is an integral part of this analysis. This method is applicable when the plane deformation cannot be applied. This method can still be applied when the seismic intensity is taken into account. This method has been used in digital computers and introduces some examples.
