摘　　要：综合考虑深基坑工程的空间效应及测点滞后设置等工程因素，利用Ｂｏｔｚｍａｎｎ叠加原理，建立了非均布初始地应力条件下的粘弹性蠕变位移反演模型，编写了相应的程序，应用于工程实例，得到了满意的结果。A comprehensive consideration is made of the engineering factors such as the time and space effect concerning with the deep located foundation pit ′s engineering, and its time delay of setting up the spot being measured, on the basis of which, applying the principle of superposition pointed out by Botzmann, the paper establishes the inversion model about viscoelasticity creeping displacement under the conditions of the earth initial stress being not uniformly distributed. In addition, the paper compiles the relative program which has received a special and satisfactory result after the use in practice in engineering.
