摘要

受场地地质条件的限制，很多建筑物采用高压缩性的软土作为天然地基，软土地基的不均匀沉降会威胁到结构的安全。不均匀沉降受上部荷载、结构刚度以及土层的不均匀性等因素的影响，传统的分层总和法不能全面地考虑这些因素。因此需要一种更为有效的分析方法来预测建筑物的沉降情况。采用结构、基础与地基共同作用的分析方法，对一栋倾斜的砖混建筑物进行三维数值模拟分析。通过与实际观测结果相比较，证明该方法能很好地分析建筑物的不均匀沉降情况。

Abstract

Restricted by the field condition

many buildings were constructed on high constrictive soft soil. The differential settlement of soft soil may threaten security of constructs. There are so many influential factors

including the differences of loading

structure stiffness and soil layer

etc.

of which all affect the differential settlement. Traditional layerwise summation method can’t take all those factors into account. Therefore

it is necessary to improve one effective method to forecast the settlement of buildings. Based on the conception of construct

substratum and foundation interaction

a 3-D numerical simulation model of a brick structure is established and its settlements are analyzed. The result proves that this method can analyze the differential settlement of oblique buildings effectively.
