逆作法施工中劲性钢柱节点施工技术方案对比分析研究

Study on Comparative Analysis of Construction Technical Schemes of Stiff Steel Column Joints in Top-down Method Construction

本文以地理位置复杂、基坑深的某工程为例,探讨了地下室逆作法施工时劲性钢柱安装技术,通过三种方案的比较,形成了劲性钢柱逆作的施工工艺,以期为含有劲性钢柱的逆作法工艺提供借鉴。

Taking a project with complicated geographical position and deep foun- dation pit as an example, this article probes into the installation technologies of stiff steel columns in top-down method construction of basement, and forms the top-down con- struction technology of stiff steel columns, in the hope of providing reference for topdown technology including stiff steel columns.
