摘　　要：三河口拱坝为国内已建的第二高碾压混凝土拱坝,其结构复杂,综合难度大。通过仿真计算分析非线性超载情况下三河口高拱坝安全度,进行综合技术评判,初步给出拱坝的安全度,与类似高拱坝工程进行对比分析,明确坝体应力状态及发展趋势,提出坝肩岩体的相对薄弱部位,并建议进行相应工程加固处理处理,保证拱坝结构安全运行,为类似工程设计提供非常有益参考。Sanhekou arch dam is the second highest roller compacted concrete arch dam in China,which has complex structure and great comprehensive difficulty.The safety degree of Sanhekou high arch dam under nonlinear overload is analyzed by simulation calculation,and the comprehensive technical evaluation is carried out.The safety degree of arch dam is preliminarily given.Compared with similar high arch dam projects,the stress state and development trend of dam body are clarified,and the relatively weak parts of dam abutment rock mass are put forward.It is suggested that the corresponding engineering reinforcement treatment should be carried out to ensure the safe operation of arch dam structure,which provides a very useful reference for similar engineering design.
