| 中文摘要 | 滑坡类型、规模、滑动面的位置及其影响距离等滑坡特性的有效预测,将有助于规划合适的减灾工作以减少滑坡灾害所带来的损失。利用强度折减有限元法与非饱和非稳定渗流有限元分析相结合的流固准耦合方法对滑坡模型试验进行了数值分析,结果表明:该法在描述降雨条件下边坡变形至失稳过程等方面具有明显的优势,即可用以预测滑坡的类型与规模以及潜在滑动面的位置,并可对滑坡的影响距离进行合理的定性分析与描述,因此,该法对滑坡减灾工作具有实用价值。; The prediction of landslide characteristics is very important for the mitigation of landslides. A discussion is presented on the practicability of the numerical analysis for quasi-coupled flow-deformation which is used to predict rainfall-induced landslide. This method, combining the finite element method for seepage and the finite element method with consideration of shear strength reduction (SSRFEM), is used to analyze two series of landslide model tests. It is shown that this method can predict the type of landslide and potential slip surface. It can also give the qualitative analysis and description of the run-out distance of landslide. Hence, the combination of the seepage finite element method and the SSRFEM is expected to be a practical method for the mitigation of landslide.; 国家自然科学基金重点项目(40534021); 长安大学科技发展基金项目(2008Z04); 中国博士后科学基金项目(20080441160) |
