摘要:

基于渗流理论,运用FLAC3D软件对南昌市某深基坑的开挖变形进行数值分析。通过模拟得到深基坑在不同开挖深度的水平位移、竖直位移分布规律,并进一步针对基坑在不同的支护措施下变形特征进行分析。研究结果表明:工程中所采用支护体系将坑外地表沉降及围护桩的变形控制在允许范围内,保证了基坑的稳定性,这可为基坑工程设计和施工提供参考。

Abstract:

Based on the seepage theory,the numerical analysis software FLAC3Dwas used to analyze the deformation of deep foundation pit excavated in Nanchang. Through analyzing different excavation depth of the deep foundation pit,the regular pattern of horizontal and vertical displacement were got. Then,the deformation characteristics under different support measures were analyzed. The results show that the support system used in the project limits the the subsidence outside of the pit and the deformation of the pile within the allowable range,and the stability of the excavation are ensured,which can be used as a reference for similar projects.
