摘　　要：城市综合地下空间工程往往存在基坑群交叉施工相互影响的问题,由于基坑群各单体基坑距离较近且施工周期交错,其受力变形和对周边环境的影响更为复杂。本文以某典型地下空间工程为背景,结合工程特点和难点分析基坑群交叉施工环境变形影响因素,归纳总结基坑群交叉施工环境影响变形控制思路和控制方法,提出工程变形控制及安全保障措施。分析成果对保证该工程的顺利实施具有重要意义,同时,可为今后类似工程提供理论基础及经验指导。Urban comprehensive underground space engineering often has the problem of mutual influence of foundation pit group cross construction.Because the distance of each single foundation pit of foundation pit group is close and the construction period is staggered,its stress deformation and influence on the surrounding environment are more complicated.Based on a typical underground space project,this paper analyzes the influencing factors of environmental deformation in the cross construction of foundation pit group according to the characteristics and difficulties of the project,and summarizes the control ideas and control methods of environmental deformation in the cross construction of foundation pit group,and propose measures for engineering deformation control and safety assurance.The analysis results are of great significance to ensure the smooth implementation of the project.At the same time,it can provide theoretical basis and experience guidance for similar projects in the future.
