基于文克尔假定的建筑物组合折面基础应力计算方法

Foundation stress calculation method based on Winker assumption for combined folding surfaces of buildings

为了解决建筑物基础面为"组合折面"的基础应力计算问题,笔者利用刚体转动前、后其上任意点新、老坐标之间为正交变换和文克尔假定,定义出刚体的位移模式和力的平衡方程式。据此可求得正交矩阵各向量元素的值,继而计算出基础面上各点的应力。

In order to resolve the issue of foundation stress calculation for ＂combined folding surface＂, i.e. , the building foundation sur- face, the author, by use of the orthogonal transformation between the new and old coordinates of any point on the rigid body before and after rotation and Winker assumption, defines the displacement mode of the rigid body and the force-balance equation. Accordingly, the values of the vector elements of the orthogonal matrix can be obtained, and the stress on any point of the foundation surface can be calculated.
