带横缝拱坝的非线性地震响应

Nonlinear seismic responses of arch dams with joins

本文运用非线性有限元方法研究了具有横向建筑缝的拱坝在地震作用下的响应，模拟了横向建筑缝的连续、张开、闭合、相对滑移等多种受力状态，并给出了算例．

Nonlinear responses of arch dams which possess of transverse construction joints(TCJ)to earthquake excitations are analysed with nonlinear FEM in this paper.Several stress states such as the continuity,opening,closing and relative sliding of the TCJ are simulated in the mathematical model.Dam-water interactions are solved by using the method combining FEM with SEMI-INFEM.The stress,displacement and response process at the important locations of the dam are demorstrated in an example.
