摘要

摘要: 根据渗流场和位移场耦合机理 ,结合某大型船闸工程 ,采用有限元法进行计算分析和对比 ,结果表明船闸在开挖过程中 ,渗流作用力对开挖边坡的稳定性影响很大。并指出对高边坡进行稳定分析时 ,正确考虑渗流作用力的影响十分重要。

Abstract: Based on the coupling mechanism of seepage field with displacement field, the effect of seepage on the displacement of high rock slope in a certain large boat gate project is studied in this paper. By use of finite element method, the seepage field and displacement field are calculated. The result shows that there is a significant effect of the seepage force on the stability of the rock slope. It indicates that a correct consideration of seepage force in analysis of high rock slope stability is very important.
