在德国北部进行的WESER隧道施工中,由于遇到了特殊地质环境,促使了复合盾构技术的提高并达到极限。由于土层非均匀性质,用来推进的技术必须具有挖掘岩石和软土的能力,同时还要具备以下功能:(1)能控制无凝聚力而松散材质的隧道不稳定工作面;

In the WESER tunnel construction in northern Germany, due to the special geological environment, the composite shield technology has been promoted and reached the limit. Due to the heterogeneous nature of the soil, the technology used for propulsion must have the ability to excavate rock and soft soil while also having the following functions: (1) unstable tunnels capable of controlling unconsolidated and loose material;
