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,成为制约盾构施工水平上一个新台阶和拓展盾构使用范围的瓶颈。
With the development of the national economy, more and more cities and subways use advanced shield construction methods. The composite EPB shield machine has been widely used as the main model. At the same time, because of the narrow adaptability of shield cutter and cutter to strata, excavation will be greatly affected in the event of a sudden change in geological conditions, and even serious damage to equipment will result. How to quickly and accurately judge geological conditions, select reasonable driving modes and driving parameters, especially how to pass the geological special sections smoothly and safely become the bottleneck restricting the construction level of shield shield and expanding the scope of shield application.
