| 摘 要： | 采用临界滑动场理论,并根据软基上堤塘的特点加以改进,结合实际堤塘滑坡实录,分别计算了不同c、以及不同填土容重下的临界滑动场,得到了相应的临界滑动面,结果与实际破坏面基本一致,在数值计算的基础上分析了滑坡的物理成因,并计算了加固方案的稳定性。计算表明,临界滑动场理论是一种非常有效的稳定性分析方法。

| Abstract: | Using a theory of critical slip field, which has been further modified to be adequate the sea embankment on soft soils, and considering the case history of a sea embankment landslide, a series of critical slip fields have been determined incombination with different c , and values of fills. The computed location of thecritical slip field is coincident nearly with the actual failure surface. Based on numerical modeling, the mechanism for landslide is analyzed an the stabilization measures are proposed. The result of analysis shows that the theory of critical slip field is rather effective for slope stability analysis and is deserved to be applied to practical problems such as those on soft soils. |
