Study on Construction Scheme for Attached Underground Structures Adjacent to Subway Station
摘要
Abstract
The underground structures of the Daoxianghu subway station of Beijing metro line 16 are adjacent to the north side of the subway station,sharing the same retaining piles with the north side of the station. For the needs of subway civil air-defense gates and pedestrian passages, the common retaining piles need to be cut off. The original design of the underground structures would have adverse effects on the operation of the subway station. Considering the impact on subway station operation due to the cutting of the retaining piles, this paper proposes the scheme that the 2nd basement of the underground structures is constructed first,the 1st basement is divided into three parts, and each part uses different construction scheme. The results of the numerical simulation of the key construction conditions show that the proposed scheme has no obvious adverse effect on the middle plate structural stress. The monitoring results of retaining piles deformation also indicate that this scheme can meet the safety requirement of the retaining structure. The construction scheme of underground structures has been successfully implemented, providing references for future construction scheme design of attached underground structures to the subway station.关键词
