围堤防渗加固及其效果分析

Analysis of Impervious Reinforcing Plan of Dyke and Impervious Effects of Reinforced Dyke

针对某水库防渗加固工程,对防渗措施进行了分析,在此基础上选择典型断面,应用数值分析方法,计算了加固后测压管水位值.分析了实测数据,对围堤测压管实测值与计算值进行了比较.结果表明,本工程所选加固方法效果良好,能够达到预期防渗效果,满足设计要求.

The measures for seepage control of a dyke were analyzed. Typical cross-sections of reinforced dyke were chosen, and analyzed by FEM. Piezometric head was obtained. Compared with measured dada, the calculated results were acceptable. The results shown that the impervious reinforcing plan of the dyke was fit, the reinforced dyke can meet the technical specifications and with the designed reservoir level, the performance is perfect.
