摘要
沉降与应力计算是水工建筑物结构设计中一个十分重要的部分。在计算过程中为避免出现基底拉应力,本文引用有限元中的接触单元模拟建筑物底面与地基面之间的接触情况,计算各个建筑物之间的绝对、相对沉降和位移,与传统的分层总和法相比,该方法能够获得更准确合理的结果,为首部结构设计提供参考和依据。
Settlement and stress calculation is a very important part of hydraulic structure design.In order to avoid the tension stress of the base,the contact element in the finite element is used to simulate the contact between the base and the foundation of the building,and the absolute and relative settlement and displacement of each building are calculated.Compared with the traditional hierarchical summation method,this method can obtain more accurate and reasonable results,and provide reference and basis for the primary structure design.
