摘要：
By Changsha Xiangjiang River Camp Road tunnel geological conditions and the overall analysis, the paper proposed the overall and the inner contour design of the underwater tunnel interchange segment .Establishing calculation model of the north-south main line and C, D segments interchange ramp, and using ANSYS finite element software to calculate and determine the design parameters of the tunnel cross-section. For the upper and lower layers tunnel use excavation construction, and applying the Center-Cross-Diaphragm (CRD) method to tunneling.
