| 摘 要： | 采用大型岩土专业有限元计算软件GeoStudio对水电站围堰渗流场及稳定性进行了数值模拟和分析,得出渗流场各要素分布图,并对围堰边坡稳定性进行了评价.研究结果表明,布置压坡透水体对提高堰体稳定性有明显作用;合理地减小围堰防渗墙深度对边坡影响不大.本文的研究结果给设计方案的修改提供了依据,对类似工程应用也有参考价值.

| Abstract: | The seepage field and stability of the cofferdam is numerically simulated using large-scale finite element software GeoStudio which is suitable for geo-technical engineering and the obtained result is analyzed.The distributions of the various parameters of the seepage field are obtained,and the stability of the side slope of the cofferdam is evaluated.The results show that,the arrangement of water-penetrating body in the slope can obviously raise the stability of cofferdam,the reasonable reduction of the depth of the cofferdam cutoff wall don't produce great influence on the side slope.The obtained results can provide reference for the revision of the design plan of the cofferdam and the design of similar project. |
