混凝土防渗墙在马房水库除险加固工程中的应用

摘要

The reinforcement project of Ma-Fang reservoir are based on the anti-seepage of dam foundation and dam itself. Through the comparative analysis of the two schemes about concrete diaphragm wall and the high pressure jet grouting pile, it concludes the first one. Then the construction technology and the effect of concrete diaphragm wall on the finite element analysis and experimental data has been stated. Comprehensive analysis shows that the concrete diaphragm wall has the characteristics of good anti-seepage, and higher reliability, so it's a practical measure in reservoir dam reinforcement.%马房水库的除险加固工作以坝基和坝体防渗为主。对混凝土防渗墙和高压旋喷桩两种方案进行对比分析，最终确定混凝土防渗墙方案。同时对该方案的施工技术和方案实施后的效果进行了有限元分析和实测数据分析。综合分析说明防渗墙具有防渗效果好、可靠性高等特点，是水库大坝防渗加固较好的措施。
