多层地下室逆作法施工关键技术研究

Research on Key Technology of Reverse Construction in Multi Storey Basement

以昆明某超高层建筑地下室逆作法项目为例,针对工程地质复杂的岩溶地质以及场地周围结构物敏感的特点,详细研究了地下室各结构施工工艺,顺逆作接口节点施工处理、结构分区划分以及超重荷载顶板加固、永临结合转换技术等。

Taking the project of the basement reverse method of a super high rise building in Kunming as an example,in view of the complex karst geology and the sensitive characteristics of the structure around the site,the construction technology of the basement structures is studied in detail. The construction processing,the partition division of the structure,the reinforcement of the super heavy load roof and the permanent combination conversion are studied in detail.
