Safety Analysis of Shield Tunnel Segment Lining Based on Field Test
[摘要] During the construction of the Nantanhai Shield Tunnel, some pressure sensors are installed to monitor the formation pressure of the segment lining. Based on the field test of Nantanhai Shield Tunnel, ANSYS software was used to calculate the mechanical model of plane strain according to structure and load pattern. Through the result, we find that the internal force of the lining of the tunnel meets requirements, and then we calculate the safety factor of the shield tunnel segment lining, And proposed the optimization of parameters.
