宜昌市东山运河堤外坡稳定性分析及其治理

Stability Evaluation and Treatment for Outer-Bank Slope of Dongshan Canal in Yichang City

宜昌市东山运河堤外坡沿途多处有河水渗漏、坡体变形严重的现象,研究其稳定性及其工程治理措施,对确保运河沿岸城市建筑安全有重要意义.采用刚体极限平衡法和有限单元元法分析和评价了三江化学动力有限公司科研中心所在运河段堤外坡的稳定性,计算分析表明,局部边坡段在各种工况下整体稳定性均不能满足规范要求,并提出了相应的治理措施.

There are many seepase and deformation phenomena at the outer-bank slope of Dongshan Canal in Yichang City. So it is very important to evaluate the slope stability and to reinforce it so as to protect the city buildings along the canal from seepage. By using rigid limiting equilibrium method and finite element method, the bank slope stability has been analyzed and evaluated. The results show that the part of the slopes is unstable and some proper treatments are required.
