【Abstract】 In order to reduce collapse damage to tunnels, based on the example of engineering in a shallow loess tunnel with a large section, the method of real-time monitoring of and early alarms for tunnel collapse is put forward. The principles of establishing early-alarm benchmark values and standards for early-alarm grading are presented, and an early-alarm system for tunnel collapse prevention(both hardware and software) is developed and tested on site. Testing results show that the hardware and software are reliable and adaptable to complex tunnel construction environments, the acquisition and transmission of data from the testing instruments performs normally, and the software system data vary with the real-time monitoring data, resulting in a grading of alarms.更多还原
