Abstract:
A Ji'nan subway station located in spring area adopted superimposed structure, facing big construction risk. Therefore, opening elongation technique was adopted in shield interval construction and concrete plus fiber glass bar diaphragm wall was set at opening, to successfully reduce the construction risk and ensure the earth stability around the shield tunnel.
