摘要
由于膨胀土滑坡土体的特殊力学性质和滑动时受到扰动,滑坡体稳定分析中的重要指标——抗剪强度很难用一般试验方法确定。采用多维图解反算法可以准确方便地确定膨胀土地区滑坡土体的抗剪强度指标,膨胀土滑坡的具体算例说明了该方法的有效性。
Because of special mechanical characteristics of expansive soil and disturbance of sliding, it is hard to obtain the soil shear strength parameters by general shear experiments in lab. Whereas, shear strength of soil is crucial in the stability analysis of landslide. The method of back calculation with multidimensional chart is given to calculate soil shear strength of landslide in expansive soils conveniently. The validity of the method is shown by computation examples.
