| 摘 要： | 针对海底隧道开挖后的复杂受力状况,采用围岩变形控制理论作为隧道施工工艺的安全控制标准.在厦门翔安海底隧道的A1标段主隧道F4风化深槽施工现场,埋设应力盒与多点位移计,对隧道开挖后围岩应力与位移进行测试,分析围岩应力与位移规律的非线性关系,在此基础上对围岩稳定状况做出初步评价,认为工程所采用的先注浆、后爆破开挖的施工工艺切实可行.

| Abstract: | Surrounding rock deformation control theory is adopted as the safety control standard of tunnel construction against the complex stress conditions.In order to measure the surrounding rock stress and displacement after excavation,pressure cell and multi-point extensometers are buried in A1 section main tunnel F4 weathering deep groove of Xiamen Xiang'an seabed tunnel.The nonlinear relation between surrounding rock stress and displacement is analyzed according to the testing results.Thus,stability situation o... |
