Problems solved by technology

[0002] A detailed and comprehensive investigation of the types, distribution and extent of tunnel damage is the premise of preventing tunnel damage, and cracks and water seepage are the main manifestations of mountain tunnel damage. A systematic investigation of them can deduce the cause of the disease , to provide a basis for the diagnosis of the health status of the tunnel. At present, there is no systematic method for on-site investigation of tunnel diseases in China.

Abstract

The invention discloses a researching method of alpine tunnel hazard, which comprises the following steps: adopting arch line as standard to divide the tunnel into left and right semi-arches and road to research; recording sectional position, sectional part, fracture incidence, fracture length, fracture breadth, pH value of leakage, fracture shape and leakage pattern in the tunnel; sketching the multiple fractures and complex position of fracture; using digital camera to pick up photo or video; proceeding rebound experiment when doubting the concrete strength of fracture part. The invention can do specific and overall on-site research for kinds of hazard for tunnel based on observation and simple measurement, which redisplays the three-dimensional hazard on the computer.

Description

technical field [0001] The invention relates to a method for on-site investigation of diseases of built mountain tunnels. Background technique [0002] A detailed and comprehensive investigation of the types, distribution and extent of tunnel damage is the premise of preventing tunnel damage, and cracks and water seepage are the main manifestations of mountain tunnel damage. A systematic investigation of them can deduce the cause of the disease , to provide a basis for the diagnosis of the health status of the tunnel. At present, there is no systematic method for the on-site investigation of the tunnel disease in China. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a method for systematic on-site investigation and recording of the defects of the built tunnels. This method can be used to carry out detailed and comprehensive investigations on various diseases existing in existing tunnels, find out the types, distributio...
