高速铁路隧道喀斯特发育区处理关键技术研究
Research on Key Technology of Karst Development Zone Treatment in High-speed Railway Tunnel
摘要
Abstract
As a common special bad geology,karst is very easy to cause surrounding rock deformation and tunnel col-lapse in tunnel construction,which has a serious impact on engineering safety and later line operation safety.In this paper,a new high-speed railway tunnel in Jilin Province is taken as an example.The geological radar is used to detect the hidden karst in the karst tunnel section.According to the development degree of karst,the construction and disposal technology of karst cave and karst fissure is formulated.The karst tunnel section is treated by adding protective wall,strengthening tunnel support parameters,advanced grouting support,karst cavity backfilling,backfilling grouting and other measures.At the same time,the numerical simulation of the disposal scheme is carried out to analyze the stress characteristics of surrounding rock and tunnel struc-ture.In the construction process,real-time monitoring is strengthened,and the development of lava is contin-uously detected,which verifies the construction disposal effect and effectively ensures the smooth implementa-tion of the project.关键词
