| 摘 要： | 以胶州湾海底隧道右线与匝道交汇洞段为背景，采用工程类比和数值模拟分析，对小净距隧道的施工顺序，超大断面隧道的开挖方法及支护参数进行了研究，结果表明:小净距隧道采用匝道先行，衬砌跟进，主隧采用CD法开挖可最大限度控制围岩塑性区;大断面洞段在进行超前注浆加固后，加强支护可实现台阶分部开挖。

| Abstract: | Taking intersection hole between right line and ramp of Jiaozhou Bay Subsea Tunnel as the background,the construction sequence of neighborhood tunnel,excavation method and supporting parameters of super large-section tunnel are studied in this paper through engineering analog and numerical simulation.The results show that first ramping and then lining for neighborhood tunnel with CD excavation method for the main tunnel can control the plastic zone of surrounding rock to the maximum extent;after pre-groutin... |
