摘要

摘要: 以一实际泥质软岩高边坡为分析对象,通过原状土样的室内试验成果分析了该种土体的特殊力学特性;采用Bishop圆弧滑动法对边坡在天然状态、残余强度状态、湿化状态下的整体稳定性进行了计算;根据试验得到的Duncan模型参数对边坡在不同应力状态下的非线性应力-应变特征进行了有限元分析;并在不改变模型参数和计算方法的前提下对加固后的边坡进行了相应的计算,所得出的结果与边坡实际运行状态吻合,表明泥质软岩边坡的设计与分析必须考虑水的入渗和卸荷松弛所导致的土体强度的衰减。

Abstract: The slaking stability of an excavated high slope of argillaceous soft rock is systematically studied. Based on the laboratory test results of undisturbed sample, the special mechanical characteristics are analyzed. The Bishop’s circular arc analysis is used to calculate the overall stability of slope in the natural state, residual shear strength state, as well as slaking state. According to the coefficients of Duncan model gained by laboratory tests, the nonlinear stressstrain characteristics of the excavated high slope under different stress state is studied by finite element method.Moreover, strengthened slope is calculated and analyzed using homologous model and coefficients. The results reveal that it is identical with the slope in the real state. The conclusion can be drawn that the strength attenuation due to rainfall infiltration and decompression relaxation must be taken into account in the design and analysis of argillaceous soft rock slope.
