| 摘 要： | 在直接法位移反分析的基础上，针对岩体结构面的变形特征提出了加权位移反演法，用现场实测位移来反演求取可能的控稳结构面的力学参数，并用灵敏度分析证实了该方法的正确性。最后利用加权位移反演法计算得出了某工程岩坡３条顺层缓倾角泥化夹层的ｃ，ｆ值，结果表明加权位移反演法具有较高的实用价值。

| Abstract: | Base on the displacement back analysis and in accordance with the special characteristics of structural planes in rock masses, the weighted displacement back analysis is introduced to determine the parameters of possible stable control planes using in site measured displacements. Then the validity of weighted displacement back analysis is proved through sensitivity analysis. As an example, the parameters c,f of some siltized intercalation in a rock slope of a practical project are obtained by the use of this method. The results show that this method has high practical value. |
