| 摘 要： | 结合厦门东通道海底隧道工程，对海底隧道最小岩石覆盖层厚度、水压力设计值的确定，衬砌结构断面优化与防排水方案，穿越海底不良地质段（断层、溶槽）的施工措施及服务隧道设置的必要性问题进行了分析。提出应从围岩稳定性和隧道涌水量的大小综合考虑最小岩石覆盖层厚度；采用限量排放的防排水方案对海底隧道较为适宜；施工中可采用注浆和冻结法穿越海底的不良地质段；设置服务隧道有利于隧道施工和运营管理。

| Abstract: | Combined with subsea tunnel engineering at eastern route way in Xiamen,the minimum rock covering thickness of subsea tunnel,water pressure design values,section optimization of lining structure and waterproof and drainage project,construction measures throughout bad subsea geology section,such as fault,solution groove,necessity of service tunnel setting were analyzed.Authors gave the minimum rock covering thickness with comprehensive consideration of stability of surrounding rock and tunnel seepage volume.Authors also put forward that waterproof and drainage project using limitation control was suitable;slip-casting and freezing method could be used throughout bad geology section;service tunnel setting was beneficial to the tunnel construction and running management. |
