摘要
结合某大型水电站溢洪道工程材料特性,采用大型有限元分析软件模拟施工过程计算了不同起浇时间下施工期及运行期溢洪道挑流鼻坎的温度场及温度应力场。计算分析表明,只要选择合理的施工方案,严格按照施工进度进行施工再加以相应的温控措施,挑流鼻坎段的温度应力能够满足设计要求。
Based on Duncan e-B model, the proposed project of a homogeneous earth dam with seepage prevention concrete wall on foundation, according to the design and construction features, the stress deformation was analyzed by means of finite element analysis. The calculated was conducted by step loading-unloading methods, the actual loading and staging mock dam phases of the process of unloading, was followed by calculation of the dam construction period. The distribution law of stress deformation was shown by the results of this study, which may provide some basis for engineering design.
