摘要
采用悬臂梁振型分解反应谱法研究重力坝地震响应.提供了不等间距的悬臂梁柔度计算公式,考虑了地震动水压力的作用与地基弹性的影响,研制了相应的计算程序.利用该程序对古田溪一级重力坝进行了地震烈度7度的抗震计算,得出了一些有价值的结论.
The mode-superposition response spectrum method of cantilever is used to study the seismic response of gravity dam. Flexibility equations of the cantilever with inequable length elements are provided, the dynamic water pressure and foundation elasticity considered, and a relevant computer program is developed. By using this program, seismic calculation of the Gutianxi first cascade gravity dam under the earthquake of intensity 7 is carried out, and some valuable results are obtained.
