摘要
调水过程中的高填方渠道类似地上悬河,其边坡稳定性对渠道安全运行具有重要影响。基于极限平衡理论,采用定量分析法对高填方渠道边坡变形进行分析。采用GEO-studio软件,研究高填方渠道边坡在自身重力载荷和堤顶荷载耦合作用下的变形情况。研究表明,高填方渠道边坡在施工期第一主应力、第三主应力变化不大,但在实际运行中有较大差别。对比空载、1/3载荷、满载荷3种工况,满载荷的高填方渠道边坡变形量最大。
The water in the process of high filled channel like hangingriver,has an important influence on the safe operation of the channel slope stability. Based on the theory of limit equilibrium,the slope deformation of high filled channel were analyzed by quantitative analysis method. By GEO-studio software to study the deformation of high filled channel slope under its own gravity load and embankment load coupling effect. Research shows that the canal slope high embankment in construction period first principal stress,the third principal stress did not change,but in the actual operation of a larger difference. Comparison of 1 /3 load,full load and no- load three conditions,high fill channel slope deformation maximum full load.
