紧邻超高层建筑群大型地下高铁车站开挖及结构盖挖逆作法施工技术

摘要

During the construction of the large underground station in downtown,the safety of the near buildings and station structures always demands more attention.The construction methods and technologies are the key constraints and challenges to the whole engineering.So,this paper introduces the engineering practice of the excavation of large span,enormous volume pit close to high-rise and cover and top-down inverse method in combination of the choice and its application of the engineering technology for Guangzhou-Shenzhen Passenger Dedicated Railway so as to provide reference for similar projects.%在城市中心区大型地下车站施工中,周边建筑物和主体结构安全通常都会受到格外的重视。工程实施方法和技术的选择成为工程顺利开展的关键制约因素和挑战。结合广深港客运专线福田站超大型地下车站的施工技术选择和实施过程,重点介绍该紧邻超高层建筑群的大跨度、大体量、深基坑开挖及结构的盖挖逆作法实施情况,以期对同类工程提供借鉴。
