摘　　要：针对地铁车站及综合开发地块的大型深基坑施工对周边建(构)筑物产生的影响,分析了不同工况下开挖至基底后的基坑变形以及周边建筑物的沉降、侧移情况。通过水平注浆土体加固并结合各种辅助施工措施,有效控制了周边建筑的变形,确保了土方开挖和基坑施工的安全。As to the influence of the construction of large deep foundation pit in metro station and comprehensive development block on surrounding buildings,the deformation of foundation pit after excavation to the base in different working conditions and the settlement and lateral displacement of surrounding buildings are analyzed.Through horizontal grouting soil reinforcement combined with various auxiliary construction measures,the deformation of surrounding buildings is effectively controlled,and the safety of earthwork excavation and foundation pit construction is ensured.
