摘要
江河堤防必须考虑河水涨落的非稳定渗流计算来设计最经济可靠的渗控措施。现结合工程实际情况,考虑洪峰水位,拟对15m深水泥土截渗墙截渗为主,辅以反虑层保护出口的方案,研究高侧渗条件下方案的渗控效果。
The most economical and reliable seepage control measures of the river levee should be designed with the consideration of unsteady seepage because of the water fluctuation.Taking the real project situation as a background,and considering the peak flood level,the seepage control effects of the program under the condition of high lateral seepage was studied,which took the 15 meter deep cement cut-off wall as the main method,at the same time the export was protected by the invert filter layer.
