摘　　要：防渗墙作为改善土石坝渗漏坝段防渗性能的重要设施,评估其加固后的防渗效果是保障大坝安全运行的关键,其中监测资料是评估防渗墙防渗效果的重要依据。以茅东水库渗漏坝段防渗墙加固工程为例,防渗墙加固前在渗漏坝段布置渗流压力测点。通过收集整理相关渗流监测数据,结合实测数据的大坝渗流参数反演,对比分析加固前后大坝不同部位渗透性变化,提出针对渗漏坝段防渗墙加固效果的综合评估方法。As an important facility to improve the anti-seepage performance of the seepage dam section of earth and rockfill dam,the evaluation of the anti-seepage effect after reinforcement is the key to ensure the safe operation of the dam,and the monitoring data is an important basis to evaluate the anti-seepage effect of the wall.Taking the anti-seepage wall reinforcement project of Maodong reservoir seepage dam section as an example,seepage pressure measurement points are arranged in the seepage dam section before the anti-seepage wall reinforcement.Through collecting and sorting the relevant seepage monitoring data,and combining with the seepage parameters inversion of the dam measured data,the permeability changes of different parts of the dam before and after reinforcement are compared and analyzed,and a comprehensive evaluation method for the reinforcement effect of the seepage dam section is proposed.
