大跨度复杂地层地铁车站施工诱发地面沉降的工序对比
Construction sequence comparison of surface ground settlement caused by long span subway station construction in complex stratum
摘要
Abstract
Combined with the engineering characteristics and construction methods in a subway station,we select typical monitoring points and analyse the surface ground settlement regularity through the surface settlement monitoring data during the pilot tunnel and hogging construction process in the main project of the station.Results show that the settlement values of the three monitoring points are basically the same when the pilot tunnel is being constructed,but the settlement values of the middle monitoring points are much more than the monitoring points on both sides during the hogging being constructed.Group-hole effect caused by the pilot tunnel construction is the important reason that causes the surface settlement values during pilot tunnel construction much larger than the values during the hogging construction.The effect ranges of surface settlement caused by pilot tunnel and hogging construction are all about 10m in the selected monitoring sections.关键词
