摘要
某工程基坑北侧距离正在运营的轨道交通17号线站台仅25m,东侧道路地下管线极多,对变形控制极为严格。以此为例,通过科学的施工部署、合理的施工组织及信息化监测等手段,成功地将基坑开挖过程对地铁及周边环境的影响控制在设计范围内,可为类似工程提供借鉴。
The north side of the foundation pit of a project is only 25 m away from the platform of rail transit line 17 in operation,and there are many underground pipelines on the east side of the road,thus the deformation control is very strict.Taking this as an example,by means of scientific construction deployment,reasonable construction organization and information monitoring,the impact of foundation pit excavation on metro and surrounding environment is successfully controlled within the design scope,which can provide reference for similar projects.
