| 摘 要： | 采用GEOSTUDIO边坡稳定及渗流分析程序,对围堰在设计洪水位时、过水工况及降雨条件下纵向边坡渗流和稳定情况进行了分析.分析结果表明:防渗心墙对围堰和边坡具有良好的防渗作用,它增强了围堰和基础边坡的稳定性.在降雨和过水情况下,堰体内渗流场发生明显改变,应对背水坡结构进行优化或采取适当安全预防措施.

| Abstract: | The seepage stability is analyzed using the GEOSTUDIO slope stability and seepage analysis program,the cofferdam seepage stability of the slope longitudinal is analyzed under the situation of design flood in a rain fall conditions.The calculated results show that the impervious core wall has good anti-seepage effect on the cofferdam and slope,it can increase the stability of cofferdam and the slope base.In rainfall and overflow cases,seepage field within the weir body changed obviously,the structure of downstreamslope should be optimized or take proper safety precautions. |
