关于土的变形计算

Deformation Calculation for Soils

从土的应力公式着手，计算上的变形时，会导致繁复的积分式．文中展示了直接积分获得的两类积分解析式，可分别用于天然地基和拉基础的土的变形计算．用计算机处理积分解析式，比用数值积分处理，可以极大地减少机算用时，从而实现某些大型问题的求解．

A complicated and troublesome integration will be resulted in calculating the deformation of soils, when it is based on the formulae of stress distribution in the half space. Two kinds of analytical integration equations through direct integration wcre developed this paper, which can be employed for calculating the deformations of the natural subgrade and the pile foundation, respectively. The run time in the computcr operation can be exceedingly reduced when the analytical integrations is employed instead of the numerical integrations, in order that the behnical problems with enormous capacity may be solved by means of the microcomputer.
