A combined initial support system of high in -situ stress and soft rock tunnel
Abstract: After excavation, the surrounding rock of the high in-situ stress and soft rock tunnel will produce large deformation, resulting in the yield, crack, and even collapse of the initial support. This study was guided by the flexible support concept based on the energy principle, proposed a combined initial support system suitable for high in-situ stress and soft rock tunnel. The combined initial...

Construction Techniques of the Shallowly Buried Large Cross-Section Haicang Double-Arch Tunnel in Xiamen China
Abstract: Construction of double-arch tunnels involves in high risk due to their large span and special structural shape. This paper presents a case study on the construction techniques of a shallowly buried large cross-section double-arch tunnel. The subject is the Haicang doublearch tunnel which has an excavation cross sectional area of 498.8 m2 and is shallowly buried in weathered rock mass and mixed...
