摘　　要：依据京石路现场路基实际回填施工过程,进行了京石路路基填土施工对大宁水库防渗墙影响的安全性评估分析,根据计算结果分析防渗墙的应力和变形规律,探讨防渗墙的安全稳定状态。结果表明:京石路路基施工对大宁水库西堤防渗墙应力及变形影响较小,不致影响防渗墙的安全。研究成果对于类似安全评估工程具有借鉴和参考价值。Since the large amount and the differential of backfill soil in the site, the stability of the wall is influenced by the construction process. Safety influence evaluation of Jingshi Road Reconstruction on the cutoff wall of the Daning reservoir had been carried out and the stress deformation law and the stability of the cutoff wall was studied. The results had shown that the working period the engineering Jingshi Road Reconstruction had little impact on the stress and the deformation of the cutoff wall, and does not endanger the cutoff wall＇ s safety theoretically. The conclusions and suggestions are valuable for design and worth as references for the similar projects
