马家坡隧道含水细砂地质地段CRD法施工应用

The construction application of CRD construction method in Majiapo tunnel aqueous fine sand geological section

以马家坡隧道工程为例,结合其地质条件,对采取的CRD开挖辅助以真空井点降水施工措施进行了介绍,并对CRD工法的施工工序进行了详细阐述,以期为类似隧道施工提供参考。

Taking Majiapo tunnel project as an example, combining with its geological conditions, this paper introduced the used CRD excavation aided by vacuum well point dewatering construction measures, and elaborated in detail the construction process of CRD construction method, in order to provide reference for similar tunnel construction.
