| 摘 要： | 本文总结了江西省主要应用的几种土石坝加固防渗方案,结合工程实例,利用有限元软件分析了几种防渗方案下防渗墙底部的水力坡降.分析结果表明：在坝前水头相等的情况下,墙前布置＂压浆板＂的防渗方案可使防渗墙底水力坡降最小,从安全的角度来讲,此方案最优.

| Abstract: | Several treatment ways of the connection passages between the bottom of the cutoff wall and grouting curtain on strengthening earth clams in Jiangxi province were summarized in this paper. Based on a practical project, the hydraulic gradient of the bottlm of the cutoff wall on the treatment ways of the connection passage was analyzed by the finite element software. The result shows： In a certain upstream water head, the scheme which put a cementing-wall in front of the grouting curtain can make the lowest hydraulic gradient in the bottom of the cutoff wall and is the best solution in the viewpoint of safety. |
