摘要
基坑的开挖不仅关系到基坑本身的安全,对相邻建筑物或构筑物也有重要的影响,因此研究复合地基在基坑开挖作用下的力学性状具有现实意义。利用有限元分析软件ANSYS建立了在开挖条件下的复合地基的模型,并对结果进行了分析。基坑开挖会引起复合地基的位移、应力的变化,当基坑开挖距离复合地基距离较近时,对周边复合地基的影响效果较为显著。因此,开挖距离是破坏复合地基至关重要的因素。
Foundation pit excavation not only relates to the safety of the foundation, but also yield to the nearby buildings, so researching on composite foundation under foundation pit excavation has realistic significance. Compos- ite foundation model is established with ANSYS software under excavation, and analyze the results. Foundation pit excavation can cause displacement, stress change of composite foundation ,when the distance of the foundation pit, excavation depth is large, and the effect is significant on the surrounding of the composite foundation. Therefore, ex- cavation distance is the main cause of the damage in the composite foundation.
