| 摘 要： | 利用基于滑面正应力调整的三维安全系数显式解法,研究三维滑体端部作用对安全系数的影响.假设滑体中部为圆柱体,端部为各种不同的曲面,计算一系列不同几何参数组合的滑体三维安全系数.结果研究表明,端部为椭球曲面安全系数最小,以下逐次为抛物曲面,圆锥曲面,指数曲面,双曲曲面,其安全系数逐渐增加.另外,还发现无论何种端部的曲面,当...

| Abstract: | By using the explicit solution of three-dimensional slope stability based on modification of normal stress distribution over the slip surface,the influence of the three-dimensional end effects on the factor of safety is investigated.The three-dimensional geometry of the slip surface is assumed to consist of a cylinder and different curved surfaces on the ends.The values of three-dimensional factor of safety are computed with a series of combination of geometrical parameters.The computation results show that... |
