复合式土压平衡盾构机在特殊地质段的掘进方法

Tunneling method in the special Region of Complex EPB Shield Machinery

随着国民经济的发展,越来越多的城市地铁及地下工程采用先进的盾构法施工,复合式土压平衡盾构机作为主要机型得到了广泛的应用。同时因为盾构机刀盘和刀具对地层的适应范围很窄,当遇到地质情况发生突变时,掘进会受到很大的影响,甚至会造成设备的严重损坏。如何快速、准确地判断地质条件,选择合理的掘进模式和掘进参数,尤其是如何顺利、安全的通过地质特殊的地段,

The complex EPB shield machinery is popular to apply in the construction of the subway and the substructure work. However,because applied area of the cutter head and cutter of the shield machinery is very limited,the tunneling process will be influenced even to be damage in the changeable region. Therefore,whether we can choose the right tunneling method and parameters through judging the region condition quickly and accurately,especially in the special and difficult region or not,that has been the bottleneck to the development of the construction level of shield machinery.
