盾构施工方法在铁路隧道施工中得到越来越多的运用,不同的地层环境对盾构技术的要求不尽相同。盾构的施工技术受施工地段的土质影响较大,结合近几年来的施工案例,从技术层面对该问题进行分析,如何在软质土层中进行高质量的盾构施工,对盾构在软土地层穿越既有铁路的施工技术进行了深入探讨。
Shield construction methods are used more and more in the construction of railway tunnels, and the requirements of shield technology in different formation environments are different. The construction technology of the shield is greatly affected by the soil quality of the construction site. Combined with the construction cases in recent years, this problem is analyzed from the technical aspect. How to carry out the shield construction with high quality in the soft soil layer, Soft soil strata through the existing railway construction technology were discussed in depth.
