本文通过对三峡升船机塔柱结构的振动模型试验和理论计算,给出了塔柱结构在不同工作状态下的自振特性、变位曲线、地震惯性力、动应力分布、并与静荷作用下的应力叠加,得到动静力作用下的应力分布。模型试验与理论分析进行了对比,结果颇为一致。对船厢悬挂体系的抗震性能作了分析。分析成果对塔柱结构的设计提出了修改建议。
Based on the vibration model test and theoretical calculation of the tower structure of Three Gorges Ship Lift, the self-vibration characteristics, displacement curves, the seismic inertia force and dynamic stress distribution of the tower structure under different working conditions are given. Under the action of stress superimposed, get the static and dynamic stress distribution. Model tests and theoretical analysis are compared, the results are quite consistent. The seismic performance of the ship suspension system is analyzed. The results of the analysis proposed modifications to the design of the tower structure.
