摘要
为分析济南某基坑工程在动荷载作用下的稳定性,利用FLAC3D对其变形和受力情况进行模拟。结果表明:在动荷载的作用下,基坑周围变形量明显受到了基坑局部形状的影响,在明显凸出区域竖向沉降量可达0.03 m,在其他区域平均变形量为0.01 m,在位移较大区域会出现明显的应力集中。
In order to analyze stability of a foundation pit project in Jinan under dynamic loading,deformation and stress were calculated by using FLAC3D.The results show that under action of dynamic loading,deformation around the foundation pit is obviously affected by local shape of foundation pit.The vertical settlement can reach 0.03 m in obvious protruding area,and the average deformation is 0.01 m in other areas.Moreover,there will be obvious stress concentration in larger displacement area.
