摘要:本文建立了考虑拱坝、地基及库水相互作用的有限元动力方程,辅以横缝间接触力为未知量的接触问题迭代解法考虑横缝的开合和滑移,分析中地震波从地基底部输入以模拟地震时的行波效应,在地基侧边界上设立粘弹性动力边界以模拟地基的辐射阻尼效应,大坝自重和水荷载的作用效应单独计算并以初始应力方式施加。针对拱坝,对设计和校核地震作用下拱坝横缝开合、滑移变形及大坝的位移、加速度和应力响应等进行了分析,从而对大坝的抗震能力进行了合理评价。

Abstract:In this paper, considering the interaction among arch dam, foundation and reservoir, the finite element dynamic equation is established. The moving and sliding of transverse joints are calculated using iterative method. The seismic waves is input from the bottom of the foundation to simulate traveling wave effect of the earthquake and the dynamic visco-elastic boundary is established on the foundation side to simulate radiation damping effect of the foundation.The load effects of dead weight and water load are calculated solely and are applied as initial stress. For LongJiang dam, the opening and closing process of transverse joint on arch dam, sliding deformation, displacement of the dam body, acceleration and stress response are analyzed under design seismic action and check seismic, which has a reasonable seismic capacity assessment of the dam.
你看看合不合适,合适的话给点钱就可以了。。。
过程还是结果重要
