桩+内支撑支护体系在武汉某深基坑工程中的应用
摘 要:该文概述武汉某基坑在环境条件复杂、开挖深度达17 m的条件下,采用排桩+2道内支撑支护体系的基坑设计方案。通过分析、比较计算结果及监测数据,该支护体系有效地控制周边沉降及位移,确保周围建筑物的安全,可为类似工程的设计与施工提供借鉴。

Abstract: This paper summarizes the design scheme of a foundation pit in Wuhan with row piles + 2 internal support system under the condition of complex environmental conditions and excavation depth of 17 meters. By analyzing and comparing the calculation results and monitoring data, the support system effectively controls the surrounding settlement and displacement, ensures the safety of the surrounding buildings, and can provide reference for the design and construction of similar projects.

随着城市建设的快速发展,建筑物密度日益增大, 拟建工程周边都存在着交通道路、建筑物及地下管线, 对变形控制日趋严格[1-2],加之国内很多城市都限制红线外使用锚杆(索),使得基坑开挖场地愈加狭小,桩+内支撑支护结构形式逐渐成为深大基坑支护设计中首选形式之一[3]。(剩余6081字)
