摘　　要：结合工程实际,对在狭窄施工场地内,紧邻深基坑的大直径给水管的保护技术进行了研究。介绍了在变形影响较大的基坑围护、开挖阶段针对水管制定的钢板桩隔离、压密注浆、钢托架倒吊等综合性保护措施。相关措施对基坑施工过程中管线的沉降控制变形起到了非常有效的作用,为类似工程积累了经验。Combined with the engineering practice,the protection technology of large diameter water supply pipe adjacent to deep foundation pit in narrow construction site is studied.The comprehensive protection measures for existing water pipes are introduced,such as steel sheet pile isolation,compaction grouting,steel support inverted hoisting,etc.The measures play a very effective role in the settlement control deformation of pipelines in the process of foundation pit construction,which accumulates experience for similar projects.
