摘要
对传递系数法两种稳定系数的意义、坡度对瑞典法稳定系数误差的影响、Bishop等人对边坡稳定性分析极限平衡法影响深远的贡献等问题进行了分析。对传递系数法条间力假定在滑面为平面时是否合理、力矩平衡满足与否是否是稳定性计算精度的决定因素、瑞典法各土条底部法向力是否均最小等问题作出了解答。
The meaning of two kinds of safety coefficients of transmitting coefficient method, the influence of gradient on error of safety coefficient of Sweden method and Bishop＇s influence-far-reaching contribution to limit equilibrium method of slope stability analysis are analyzed. Whether the assumption of inter-slice forces of transmitting coefficient method is in reason for planar slip surface or whether moment equilibrium is a determinant of precision of stability calculation and whether the normal forces of every slice base of Sweden method is minimum, they are all answered.
