Research on Railway Tunnel Lining Crack Disease Control Measures
The number of high-speed railway tunnels in China is increasing year by year.In the process of railway joint testing and opening and operation,tunnel lining usually produces cracks,often accompanied by leakage and other conditions.Some cracks are caused by unreasonable construction technology,and the cracks are basically stable and will not produce safety risks.But some cracks are caused by shear force fail-ure;Some of them have pressurized water pressure fracturing,accompanied by water seepage,etc.,and gradually develop with time,seriously endangering the safety of tunnel structure and driving safety,and should be remedied in time.This paper analyzes the causes and treatment measures of lining cracks in a high-speed railway tunnel along the southeast coast,in order to provide some reference for similar problems.
