某堆积体边坡滑面的强度参数反演研究

Research on Back-analysis of Slide Surface Strength Parameters of a Accamulation Slopes

通过现有的资料分析,某堆积体边坡可能的破坏模式为覆盖层内部的滑动或沿滑动带的深层滑动.根据地勘资料、室内试验数据和边坡安全系数的计算方法,对边坡的岩土体力学强度参数进行反演分析.计算结果表明:建立准确的计算模型并采用参数反演所得出的结果客观、合理,通过对其他剖面的稳定性计算更进一步地验证了所得结果的合理性,为类似工程的稳定性分析以及强度参数的反演计算提供了参考依据.

Though the analysis of existing data, the possible failure modes of a overburden slope are sliding within the cover or sliding along the deep side of the slide. According to the geological survey data, the indoor test data and the calculation method of the slope safety factor, the parameters of the rock and soil mechanics strength parameters are analyzed inversion. The results show that the results obtained by using the parame- ters inversion are objective and reasonable. The stability of the results is verified by the stability calculation of other sections. This paper also provide references for the stability analysis of similar projects and the inversion calculation of intensity parameters.
