The Coefficient of Equivalent Compressive Deformation for the Settlement Calculation of Deep Foundation

本文根据弹性理论竖向应力分布的计算公式，通过引入等效压缩变形系数ψｃ，将复杂的Ｍｉｎｄｌｉｎ解答应力计算过程简化为对Ｂｏｕｓｓｉｎｅｓｑ解答应力的计算，并且给出了可供深基础沉降计算实用的ψｃ值表格及修正公式。

This paper introduces ψ c,the coefficient of equivalent compressive deformation,according to the stress distribution from elastic half space theory. As a result,it can simplify the complicated stress calculation from the Mindins solution to the Boussinesq answer. The paper also presents the table of ψ c and its modification formula for the settlement calculation of deep foundation.
