Ome隧道是一条两层公路隧道,具有220~260 m2的大断面,在疏松地层上进行浅层开挖。隧道开挖按照新奥法(NATM)进行。由于隧道在人口密集住宅区内一条道路的下方穿过,所以对隧道作业所引起的表面沉陷进行了限制。根据施工期间对地层性状的监测和分析,采用了各种辅助施工方法,如长管棚灌注支护等。在对居民和其它设施没有发生过度损害和干扰的情况下,一条长为1 060 m的隧道工程圆满竣工。
The Ome Tunnel is a two-story highway tunnel with a large section of 220-260 m2 and shallow excavation on unconsolidated formations. Tunnel excavation in accordance with the new Austrian law (NATM). As tunnels pass underneath a single road in a densely populated residential area, surface subsidence caused by tunneling operations is limited. According to the monitoring and analysis of stratigraphic characters during construction, various auxiliary construction methods are adopted, such as long pipe shed perfusion support and so on. A tunnel project of 1,060 m in length was successfully completed without excessive damage or disturbance to residents and other facilities.
