Abstract: This paper presents a case history of the construction of a deeply buried communication pilot tunnel in saturated soft soils in the River Crossing Project in Wuhan No. 2 Metro Line. The construction technique involves the freezing of the high water pressure aquifer underneath the river bottom. The design and construction of the frozen curtains and the construction techniques of the pilot tunnel are introduced and the results are satisfactory.
