以国内第一条穿城入地的石家庄隧道暗挖段为工程背景,考虑不同列车荷载工况,利用midas-gts有限元软件对其模拟计算,研究地表沉降规律和新建双连拱隧道结构受力,验证列车限速的合理性,以期为类似工程提供借鉴。
Taking the first underground excavation of Shijiazhuang tunnel in the city as the background of the project, taking into account the load conditions of different trains, the midas-gts finite element software was used to simulate and calculate the law of surface subsidence and the new double-arch tunnel structure Force to verify the rationality of train speed limit, with a view to provide reference for similar projects.
