摘　　要：武汉新龙国际项目基坑挖土施工时发现基坑变形超过预警值,部分支撑梁立柱发生倾斜甚至断裂,需采用型钢加固倾斜的格构柱。通过研究解决了梁底槽钢焊接、槽钢与支撑梁底缝隙处等难题,在型钢加工、型钢打入等工序采取技术措施,保证了基坑安全。During foundation pit excavation construction of Wuhan Xinlong International Project,it was found that the foundation pit deformation exceeded the warning limit and some support beam columns declined,even broke,so the declined lattice columns should be reinforced by section steel.After research,some difficulties in groove steel welding at beam bottom and construction at gap between the groove steel and support beam bottom were solved,and some technical measures,such as section steel process,section steel inserting,etc.,were adopted,to guarantee safety of foundation pit.
