大变形隧洞支护现状与新型让压支护发展与展望
Status quo of supporting scheme for large deformation tunnel and prospects of a new type of stress yielding supporting system
摘要
Abstract
With the rapid development of the infrastructure construction in our country, more and more deep-buried large and long tunnels are built in the areas with high geostatic stress and poor geological conditions. Large deformation of tunnels under high geostatic stress and soft surrounding rock poses a threat to the project safety. Foreign and domestic large deformation tunnel supporting system are investigated and researched. The results show that: the current treatment of large tunnel deformation in transportation, hydropower and water conservancy industries is using strong support or layered strong support, which turns out to be material consuming and ineffective in elimination of damages caused by large deformation. However in coal mining industry, a stress-yielding supporting solution is adopted and proved successful in treatment of large deformation. Through comparative anal-ysis of these two supporting solutions, it is concluded that the stress yielding supporting system overcomes the drawbacks of the current supporting system used in transportation, hydropower and water conservancy industries and has a good application pros-pects.关键词
