摘要
同马大堤汇口段是 98洪水后安徽省堤防加固示范堤段 ,通过两典型断面的渗流计算对大堤的渗流控制措施进行了分析论证 ,给出了 1998年洪水期渗流场、设计断面压土方案下的渗流场及压土方案的优化措施 ;根据该段的风浪要素核算结果和波浪作用下的渗流计算结果 ,分析了砼板护坡的稳定结构形式 ,比较了开缝砼板护坡和全封闭砼板护坡、护坡下有无垫层等几种不同情况 ,进行了砼板护坡的厚度、强度和稳定性核算 ,提出了汇口段砼板护坡稳定形式。护坡工程建成后 ,经过 1999和 2 0 0 0年汛期洪水风浪的考验 。
Tongma dike is a demonstration segment of the protective dike in Anhui Province. By use of seepage calculation of two typical sections,controlling measures were analyzed. Given are the seepage field during flood of 1998 course and seepage field of designed section with soil blanket.According to calculated results of the wind and waves factor and seepage under the action of wave, the stable structural form of slope protection was analyzed. And some different types are compared. Stable form of slope protection with concrete slab was brought up.After engineering construction, it was tested by the wind and waves during flood in 1999, and the performance is good.
