龙颈上水库土坝加固防渗设计

The design for the earth dam reinforced against leakage in Longjingshang reservoir

文章通过对龙颈上水库土坝工程地质条件的分析和土坝防渗方案的比选后,采用坝体劈裂帷幕灌浆与坝基帷幕防渗的设计方案对水库土坝实施培厚加高及防渗处理。并对处理后的坝体渗流及坝坡稳定进行了分析计算,结果表明,坝体上、下游坝坡在各种工况下,坝坡稳定安全系数均满足规范要求。

After analysis of the earth dam engineering geology condition and the seepage prevention scheme,the rip purdah grouting and dam foundation prudah seepage prevention are used to raise the height of the dam.The seepage and stabilization of the dam are calculated after the treatment,the result indicates that the stable safe coefficients are satisfying the requirement of the code under the all kinds of conditions.
