Abstract

Based on the engineering example of underground diameter project replacing the cutter teeth inside with high pressure, the application of grouting reinforcement and pile foundation reinforcement in soil strengthening was discussed. The causes of gas leakage of inside with high pressure were analyzed, and the countermeasures were proposed for assuring the normal construction of shield.
