Abstract

The invention discloses a bracket for monitoring the structural stability of a tunnel and a corresponding monitoring method thereof. The bracket comprises a plurality of arch-shaped brackets and a power supply, wherein the arch-shaped brackets are arranged in parallel along the length direction of the tunnel, and each arch-shaped bracket is vertical to the length direction of the tunnel and clingsto the inner wall of the tunnel; a plurality of stress sensors are arranged on one side, close to the inner wall of each arch-shaped bracket; and each strain sensor is connected to a communicator, and each communicator is in signal connection to data collection equipment. The method comprises the following steps acquiring strain data collected by each stress sensor is acquired by virtue of data collection equipment; carrying out difference on each strain data and preserved initial strain data of each stress sensor, and screening strain data in which a difference result exceeds a preset threshold value; and acquiring the position information of the inner wall of a corresponding tunnel according the screened strain data. According to the bracket, the unmanned and real-time monitoring of thedeformation of the inner wall of the tunnel can be realized, and the bracket is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the field of tunnel monitoring equipment, in particular to a support for monitoring the stability of a tunnel structure and a corresponding monitoring method. Background technique [0002] The continuous expansion and enrichment of the transportation network has brought great convenience to the emergence of people. Among them, the construction of tunnels and bridges has further shortened the road distance and improved the efficiency of people's travel. At the same time that tunnels bring convenience to traffic, there are also potential safety hazards in tunnels themselves-such as changes and damages to tunnel structures. And this element is an important prerequisite to ensure the safety of automobiles, so it is necessary to timely grasp the safety of the tunnel environment—such as whether there are cracks in the tunnel. [0003] At present, the inspection of tunnels is through manual regular inspections. Based on the large n...
