摘要
目的研究船闸闸室体系动力受力变形特性,分析其地震作用下船闸闸室结构-地基相互作用体系的动力响应特性,评价其抗震性能.方法采用子空间迭代法提取船闸闸室体系自然频率与振型,采用考虑几何非线性的Newmark隐式积分法求解船闸闸室动力体系方程,针对横向和竖向地震力作用下船闸闸室相互作用体系分别进行振型分解反应谱和动力时程分析.结果 3组水平地震波作用下,船闸闸室体系闸墙横向水平位移最大幅值为42.5 mm,最大拉应力为1.39 MPa.结论船闸闸室体系弹性动力时程分析与地震反应谱计算结果幅值水平相近,地震反应谱分析结果及进一步动力时程分析,船闸结构满足抗震规范要求.
In order to discuss the dynamic deformation characteristics and evaluate the seismic performance and dynamic response of interaction system including lock chamber-soil foundation,both response spectrum and time-history analyses of chamber lock interaction system subjected to horizontal and vertical seismic action are conducted respectively by using subspace iteration method to obtain natural frequencies and modes,and solving dynamic equations by New mark's implicit method with considering geometric nonlinearity based on the computational FEMmodel.The numerical results show that the maximum horizontal displacement of lock chamber and the maximum tensional stress are 42.5 mm and 1.39 MPa respectively.It can be concluded that the results from response spectrum and step-by-step integration methods accord with each other well and meet the re-quirements of the seismic code.
