| 摘 要： | 介绍了土钉支护技术,利用极限平衡理论推导了非饱和土边坡土钉支护整体稳定性最小安全系数Fs,min公式。用MATLAB计算机语言实现了遗传算法寻找非饱和土素土边坡和土钉支护结构整体稳定性最小安全系数Fs,min的自动寻优。通过对一具体工程实例分析,得到降雨入渗对非饱和土边坡稳定的一些影响规律。

| Abstract: | Soil-nail braced technique was introduced.According to the limiting equilibrium method.The minimum factor of safety for the stability of soil-nail bracing structure of unsaturated soil slope is deduced according to a limiling eguilibrium method.Genetic algorithm is introduced for searching the minimum factor of safety of natural slope and soil-nail bracing in unsaturated soil.The optimal course is automatically implemented with MATLAB.By analysing an engineering example,some results are obtained for the slope's stability as rainfall infiltration to the unsaturated soil slope. |
