摘要/Abstract

摘要： 采用动力模型试验和有限元动力分析两种手段，对景洪水电站水力式升船机塔楼结构的动力特性和动力响应进行分析研究，在此基础上对水力升船机塔楼这种新型结构抗震安全性进行综合评价。结果表明：动力模型试验和有限元数值计算的结果基本一致，塔楼结构形式合理，但由于结构较为单薄，其动力响应较为复杂，许多部位出现较大的动应力，需要采取工程措施来改善这些部位的应力状况。

Abstract: The dynamic vibration model test and FEM-based numerical calculation are adopted to study the seismic performance and further to comprehensively evaluate aseismic safety of the tower structure. The results from model test and finite element calculation are in line with each other. The results show that the form of tower structure is relatively reasonable, but dynamic response is relatively complex due to the thin structure. Large dynamic stress appear in many parts of the tower, which need corresponding engineering measures. The research can provide a scientific basis for seismic design of similar structures.
