摘    要:基于立洲RCC拱坝温度场全过程仿真分析成果,考虑施工期残余应力,分析大坝蓄水过程中在温度荷载、水荷载、渗透压力和自重作用下坝体应力变形特性及发展规律,探寻真实工作状态下与设计荷载作用下大坝应力特性差异,并结合类似工程蓄水监测成果对立洲大坝的蓄水安全情况进行分析和评价。分析结果表明,大坝实际应力、变形性态与传统算法结果相比差异显著,大坝在蓄水过程中处于弹性范围内,工作状态正常。

关 键 词:立洲RCC拱坝  初期蓄水  真实工作状态  应力变形特性

Abstract:Based on the analysis result of the whole process simulation made on the temperature field of Lizhou RCC Arch Dam, the temperature load, water load, seepage pressure during the dam impounding process and the stress and deformation behaviors of the dam and their developing laws under the effect of the self-weight of the dam are analyzed under the consideration of the residual stress of the construction, and then the difference between the stress behaviors of the dam under the actual operation condition or under the design load is researched, furthermore, the impounding safety of the dam is analyzed and assessed in combination with the achievement from the impounding monitoring of the other similar project. The study shows that the actual stress and deformation behaviors of the dam significantly differ from those obtained from the conventional calculation method, thus the dam is in an elastic state during the impounding process with a normal operation condition.
Keywords:Lizhou RCC Arch dam  initial impoundment  actual operation condition  behaviors ofdeformation and stress
