【摘要】 结合金安桥混凝土重力坝工程的抗震性能研究,对大坝按整体模型和分缝模型分别进行了动力试验。试验中考虑了横缝和动水压力的影响,得到了整个坝体空库、满库时的空间动力特性。并对大坝进行了三维有限元动力分析,与模型试验结果进行了比较,两者符合得较好。更多还原

【Abstract】 The dynamic tests on an integrated model and a model with contraction joints were carried out in order to study on the seismic performance of Jinanqiao concrete gravity dam.Considered the influence of contraction joints and hydrodynamic pressure,the dynamic responses on the conditions of empty reservoir and full one of the concrete gravity dam are obtained.The results of tests are compared with ones of 3-D finite element analysis for the concrete gravity dam.Both of results are in good agreement.更多还原
