横琴口岸及综合交通枢纽工程预留轨道交通地下空间建造技术

Reserved Underground Space Construction Technology for Rail Transit in Hengqin Port and Comprehensive Transportation Hub Project

横琴口岸及综合交通枢纽工程预留轨道交通地下空间,位于通关主体东侧,澳门出入境平台下方,场地原始地貌属于填海软土区域,地质条件复杂,因此,采用超深地下连续墙、大跨度钢骨梁吊装等技术。论文通过对比常规的结构形式,根据具体结构特点与工艺流程,分析施工特点及难点,解决施工时的问题。

Hengqin port and comprehensive transportation hub project reserve underground space for rail transit,which is located in the east of the main body of customs clearance and under the Macao entry-exit platform.The original landform of the site belongs to the reclamation soft soil area,and the geological conditions are complex.Through the use of ultra deep underground continuous wall,large-span steel beam hoisting technology,etc..Compared with the conventional structure,according to the specific structural characteristics and process,the construction characteristics and difficulties are analyzed to solve the construction problems.
