摘　　要：笔者介绍了万家口子碾压混凝土拱坝新老混凝土结合面的处理,通过外观质量及内部监测成果对已浇筑坝体进行质量检查,根据已浇筑坝体的实际情况和拟定的浇筑计划、温控措施,采用三维瞬态有限元法对施工全过程进行温度场及温度应力仿真计算分析研究,在此基础上拟定相应的层间处理技术措施。监测资料表明,这些处理措施效果良好。The author introduces the treatment of new-old concrete interface of Wanjiakouzi RCC arch dam,inspects the quality of the poured dam body through the appearance quality and internal monitoring results,and uses the three-dimensional transient finite element method to simulate and analyze the temperature field and temperature stress during the whole construction process according to the actual situation of the poured dam body and the proposed pouring plan and temperature control measures.On this basis,the corresponding interlayer treatment technical measures are worked out.Monitoring data show that these measures are effective.
