| 摘 要： | 在分析加筋土边坡稳定性时,将加筋材料的作用视为施加于滑面上的等效力,建立了满足力平衡的加筋土边坡安全系数的计算格式;将边坡临界滑动场数值模拟方法进行推广,提出了基于力平衡的加筋土边坡临界滑动场计算方法,可以得到形状任意的临界滑动面及边坡最小安全系数。通过算例,比较加筋前后临界滑动面和安全系数的变化,并探讨了加筋水平间距、强度、长度对加筋土边坡稳定性的影响。

| Abstract: | In the analysis of reinforced soil slope,the effect of reinforcing materials is considered as an equivalent additional stress acting upon the slip surface.The formulas for computing the factor of safety of reinforced soil slope are presented.An extension of the numerical simulation for critical slip field(CSF) is made.Then,a numerical scheme is proposed for calculating the critical slip field of reinforced slope based on the force equilibrium.The position of critical slip surface of arbitrary shape and the ... |
