三峡工程垂直升船机建筑结构整体抗震计算

Whole Structure Aseismic Computation of Three Gorges Project’s Shiplift

采用振型迭加反应谱法和逐步积分时程分析法对三峡升船机上闸首和前塔柱结合布置和分离布置两种方案的整体结构进行了抗震动力分析，研究了在设计地震作用下结构的安全性，塔柱和顶部机房的动力相互作用，承船厢锁定对塔柱动力响应的影响，塔柱顶相对位移能否满足大型卷扬设备的运行要求等问题。

In design stage two alternative schemes, i.e., combined scheme and seperated scheme of the upper lockhead and the upper towers were proposed. In this thesis, the aseismic dynamic analysis of the whole structure of the shiplift was investigated by means of response spectrum method and time history integration method. The aseismic performance of the shiplift structure, the dynamic interaction between towers and top engine house, the dynamic effect of the locked ship reception chamber on towers response, and problem whether the tower tops’ relative displacement will satisfy the operating requirement of huge towing machinery etc., were studied under the action of design earthquake intensity.
