Displacement characteristics of high-speed railway tunnel construction in loess ground by using multi-step excavation method
TL;DR: In this paper, a series of in-situ tests and numerical simulations were conducted to reveal displacement characteristics and obtain optimal construction approaches for large-span loess tunnels in China.
Journal ArticleDOI
Key Techniques for the Construction of High-Speed Railway Large-Section Loess Tunnels
Yong Zhao,Huawu He,Pengfei Li +2 more
TL;DR: In this paper, the authors systematically summarized the technical characteristics and main problems of the large-section loess tunnels on China's high-speed railway, including classification of the surrounding rock, design of the supporting structure, surface settlement and cracking control, and safe and rapid construction methods.
Journal ArticleDOI
A bottom-to-up drainage and water pressure reduction system for railway tunnels
TL;DR: In this article, a conceptual bottom drainage and water pressure reduction system at the bottom of railway tunnel is proposed, which includes a transverse catchment system, a longitudinal water conducting system and a bottom-to-up water drainage system.
Journal ArticleDOI
Development and assessment of a water pressure reduction system for lining invert of underwater tunnels
TL;DR: In this article, the feasibility of bottom-up drainage and water pressure reduction system for underwater tunnels has been evaluated and shown to reduce the secondary lining external water pressure on underwater tunnels.
