INTRODUCTION OF EPB SHIELD TUNNELS DESIGN AND CONSTRUCTION TECHNOLOGY:GUANGZHOU 2nd METRO LINE

摘要

Based on the related literature, the paper introduces the Design and Construction Technology of Guangzhou 2nd Metro Line: the shield tunnels from Chigang to Lujiang. And it emphasizes the following items: (1) How to select the shield machines; (2) How to confirm the segment joint stiffness and optimize the design method of segments; (3) The design theory and method of the shield tunnel lining under complicated geologic conditions; (4) The anti-seismic design method of the shield tunnel linings; (5) The field information-construction monitoring technology of EPB shield tunnels; (6) The 3D Finite Element Method simulation of EPB shield tunnelling. The gained results can be used in the shield tunnel design and construction.
