Vibration monitoring system for opencut tunnel impacted by rockfalls and monitoring method

Abstract

The invention provides a vibration monitoring system for an opencut tunnel impacted by rockfalls and a monitoring method and relates to a safety monitoring technology. The vibration monitoring systemfor the opencut tunnel impacted by the rockfalls comprises a sensor part, a collector part and a monitoring center, the sensor part comprises acceleration sensors and video monitoring devices, and theacceleration sensors are arranged and distributed on a top plate of the opencut tunnel; the visual range of the video monitoring devices includes the tunnel top of the opencut tunnel and the top plate of the opencut tunnel, and the video monitoring devices are linked to the monitoring center in a wired transmission mode; the collector part is connected with the acceleration sensors and linked tothe monitoring center through a communication network, and a monitoring center system includes an intelligent monitoring application server and a data server and is used for monitoring storage of dataand early warning information and pushing client side data. The problem is solved that it is difficult to evaluate the damage of the opencut tunnel since the structure of the opencut tunnel and the structure of a top cushion layer of the opencut tunnel are diversified.

Description

technical field [0001] The invention relates to safety monitoring technology. Background technique [0002] With the rapid development of high-speed railways in the mountainous areas of western my country, the proportion of tunnels in the lines is increasing. In order to reduce the impact of dangerous rockfall disasters on the safe operation of the line, arched open holes or shed-shaped open holes are usually set up at the exit of the tunnel. [0003] In recent years, the central-western and southwestern railways represented by the Chengdu-Lanzhou, Chengdu-Kunming, Chengdu-Guiyang, Chengdu-Lhasa railways have the common characteristics of complex geological conditions, frequent landslides, debris flow disasters, harsh environments, and Myeongdong. As an important disaster prevention and mitigation facility, structures will be in increasing demand. Due to the random and unpredictable characteristics of the occurrence time and impact kinetic energy of rockfall impacts, solid...

AI Technical Summary

Problems solved by technology

[0004] There is no railway in my country that has built a rockfall monitoring and early warning system for open-hole structures, and research on the rockfall monitoring and early-warning theory for open-hole structures has not been systematically carried out.
