摘　　要：为确保内支撑体系在基坑开挖和主体结构施工过程中能够可靠地进行竖向传受力,并能在计划工期内以及成本可控的前提下完成立柱桩的施工,需要研究一种新的型钢格构柱与立柱桩钢筋笼连接固定的方法。以横沥地下空间工程子项目2北段项目为例,通过方案比选、技术分析,确定了型钢格构柱与立柱桩钢筋笼连接固定的做法,并分析了其现场应用。经过现场施工实践,该连接固定方法具有应用上的创新性,可为类似项目提供一定的施工经验。In order to ensure that the internal support system can reliably carry out vertical force transmission in the process of foundation pit excavation and main structure construction,and can complete the construction of column piles within the planned construction period and under the premise of controllable cost,it is necessary to study a new method of connecting and fixing steel lattice columns and column pile reinforcement cages.Taking the northern section of Hengli underground space engineering sub-project 2 as an example,through scheme comparison and technical analysis,the method of connecting and fixing the steel lattice column and the column pile reinforcement cage was determined,and its field application was analyzed.After on-site construction practice,the connection fixing method is innovative in application and can provide some construction experience for similar projects.
