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.
