Analysis on Shield Station-passing Construction Technology

Shield construction is widely used in the urban metro;the urban metro generally has the characteristics such as small engineering quantity,short mileage,multi stations and a large number of turning around,etc.Station-passing plays an important role in the construction.Shield generally has a narrow space and various processes,so the reasonable shield station-passing can not only save manpower and material resource,but also can ensure the engineering quality.Based on the engineering practice,the shield station-passing construction technology has been deeply studied in this paper.
