摘要
近年来地铁在我国各地广泛发展,地铁运营期由于列车振动等引发的沉降问题也日趋明显。泥炭质地层是一种含水量高、液限和塑限极大、且承载力低的软粘土。目前,对于在泥炭质地层中修建的地铁运营期的研究也处于初级阶段。针对上述问题,本文根据昆明地铁晓东村站到世纪城站区间隧道现场实际地质资料,通过FLAC~(3D)有限元分析软件建模对在列车动荷载作用下地层及隧道结构响应规律进行数值分析、得出列车动荷载一次作用下的地层沉降;通过经验拟合的方法计算泥炭质地层在今后运营期的沉降,为今后地铁运营期的监测、维护提供指导。
In recent years,the subway is widely developed in our country,and the settlement caused by train vibration and other factors is becoming more and more obvious in subway operation period.Peat layer is a kind of soft clay with high water content,liquid limit and plastic limit,and low bearing capacity.At present,the research on the construction of the subway operation in the peat stratum is in the primary stage.For these problems,this paper accordingto the Kunming subway actual geological data from the Xiaodongcun station to the Shijicheng station,with the help of finite element analysis software FLAC3 D,the numerical analysis of formation settlement under a train load effect and mechanical response in terms of formation and tunnel structure under the train load during the metro operation in peat layer will be done.Therefor,the settlement of the peat layer in the future operation period will be calculated by experience fitting method,which provides guidance for monitoring and maintenance of metro operation period in the future.
