| 摘 要： | 通过对西部某县城商业街建筑物变形破坏特征的调查研究，结合建筑物场地地质结构条件，分析了建筑物开裂破坏的原因，并用数值模拟方法对其变形机制做了模拟分析。分析表明，该建筑物的开裂破坏与地基基础条件和临空条件密切相关，临空条件决定了结构松散的地基基础在建筑物荷载作用下，临空侧发生无侧限压缩，基础整体产生不均匀沉降，导致建筑物倾倒变形。FLAC3D数值模拟所得结果与地质分析取得了良好一致性。

| Abstract: | Through the investigation and researching to deformation failure characteristics of one building in commercial street at a city situated in a county town in west of China,combining with geological condition of the building site,this paper analyses the reason of the building deformation failure.Numerical simulation method was used to simulation and analysis the deformation mechanism.The analysis shows that the building deformation failure is closely related to fundamental conditions and free face conditions.... |
