介绍轨道交通平行换乘车站后建车站施工中的基坑外土压力特征及墙体变形性状。在采取“化整为零”的施工技术措施后,根据车站施工得到的实测监测数据,尽管具有非对称特点,靠先建车站侧变形明显偏小;在基坑开挖和回筑阶段,墙后土压力的非对称性更为明显;但在顶板完工后,土压力趋于稳定,非对称性逐渐消失。
The earth pressure characteristics outside the foundation pit and the deformation characteristics of the wall during the construction of the railway station after the parallel interchange of rail transit are introduced. According to the actual monitoring data obtained from the construction of the station, the distortion on the side of the station built earlier by the station was noticeably smaller despite adopting the construction technology measures of “uniting to zero”. In the stage of excavation and construction of the foundation pit, , The asymmetry of earth pressure behind the wall is more obvious. However, after the roof is completed, the earth pressure tends to be stable and the asymmetry gradually disappears.
