摘要
在水闸闸室抗震设计中,为充分考虑闸室结构空间振动的耦联影响,建立了能反映闸室结构实际情况的空间三维计算模型,采用振型分解反应谱法对闸室结构进行了抗震动力计算,并以嶂山闸闸室为例,结合闸室结构地震作用效应的分析结果,提出了有针对性的抗震措施,达到了减小地震作用效应、增强闸室抗震性能的目的。
In seismic design of sluice chamber, in order to fully consider the spatial structure of the chamber vibration coupling effects, a three-dimensional computational model is established to reflect the actual situation of the chamber structure. And then the aseismie dynamic of chamber structure is calculated with vibration response spectrum method. Combined with analysis of seismic effect of chamber structure, an effective aseismic measure is proposed by taking Zhang-shan sluice chamber for an example, which attains the goal of reducing seismic effect and enhancing aseismic performance of chamber.
