软基上建筑物沉降的有限元数值模拟分析

地基的不均匀沉降会引起墙体开裂,建筑物的倾斜会威胁到结构的安全,因此对建筑物沉降情况的预测分析具有非常重要的现实意义。文章运用地基、基础与结构协同作用的分析方法,对一栋倾斜的建筑物进行ANSYS实体建模分析。通过与理论计算结果相比较,证明该分析方法能很好地分析建筑物的不均匀沉降情况。

Finite Element Numerical Simulation Analysis of Settlements of Buildings on Soft Soil

Differential settlements of the foundation may result in the cracking of walls and the sloping of buildings,and that may threaten the security of constructs.Therefore,it is very necessary to forecast and analyze the settlements of buildings.Based on the conception of construct,substratum and foundation interaction,an ANAYS simulation model is established and a sloping building is analyzed.The result proves that the analystic method can analyze the differential settlement of buildings effectively after comparing with the theoretically calculated results.
