摘要
随着我国高铁规划蓝图不断延展,大型综合交通枢纽的建设也迎来全面建设的高潮。大型交通枢纽具有多种交通方式高度集成的特点,其功能模块日益复杂,这在地下工程施工中体现为纵横包络的坑中坑、坑连坑,导致围护形式更加复杂、工期相对紧张。文章以东方枢纽上海东站为研究对象,阐述了排桩偏位处理难点,分析了排桩偏位处理技术,并根据桩身侵入程度提出了相应的加固方案,不仅保障了项目的顺利实施,还为后续类似工况提供了经验借鉴。
With the continuous extension of China's highspeed rail planning blueprint,the construction of largescale comprehensive transportation hubs has also ushered in the climax of comprehensive construction.The largescale transportation hub has the characteristics of high integration of various transportation modes,and its functional modules are increasingly complex.This is manifested as interconnected and overlapping pits within pits in underground engineering construction,resulting in more complex enclosure forms and relatively tight construction schedule.Taking the eastern hub Shanghai East Railway Station as the research object,this paper expounds the difficulties in the treatment of pile row deviation,analyzes the treatment technology for pile row deviation,and puts forward corresponding reinforcement scheme according to the degree of pile invasion,which not only ensures the smooth implementation of the project,but also provides experience for the follow-up similar working conditions.
