| 摘 要： | 运用FLAC3D软件对深基坑工程的开挖方案进行数值模拟。不同的基坑开挖方案进行数值模拟，分析其对基坑变形的影响。重点研究同一基坑的不同开挖方法对基坑侧壁、支护桩、坑底隆起等变形量的影响规律。结合施工经验和数值分析，对基坑开挖方案进行设计，择优确定开挖方案，合理控制基坑变形，从而达到减小对周围环境的影响，降低工程造价和确保施工安全的目的。

| Abstract: | Various excavation programs for deep foundation pit engineering are separately numerically simulated using FLAC3D software in this paper.Different program is selected based on foundation pit to analysis its influence on the deformation of foundation pit respectively.This paper specially studies the influence law of different excavation programs for the same foundation pit on side wall,support pile,bottom heave and other deformations.Combined with construction practice and numerical analysis,the excavation program is designed and optimized to reasonably control deformation and thus minimize the impact on ambient environment,reduce project cost and ensure construction safety. |
