摘要
近几年来,防渗墙施工工艺日趋成熟并在水库除险加固工程中得以广泛应用。结合浙江省土石坝除险加固工程,建立三维计算模型,模拟计算了加固后大坝渗流场理论特征,并通过由DG-2005型智能分布式大坝安全监测系统取得的观测资料对设计进行验证,得出防渗墙起到一定的防渗作用,但理论与原型观测结果有一定差异,分析了产生差异的原因,同时提出除险加固施工中的注意事项,希望能为类似工程提供借鉴。
In recent years, construction technology for cut-off wall has become more and more mature day by day, and is widely used for reservoir reinforcement projects. In the article, a three-dimensional calculation model for earth and rock-fill dam reinforcement project in Zhejiang is built, and theoretical characteristics of dam seepage field after reinforcement are simulated. The observed data collected by DG-2005 type smart monitoring system for dam safety have verified that the cut-off wall plays a role in dam anti-seepage, and that there are difference between theoretical results and prototype observation. The reasons are also analyzed in the hope of offering reference for the similar project.
