Problems solved by technology
However, the process from instability to collapse of dangerous rocks often develops quite rapidly. The response of manual monitoring is slow, and the data collection is not real-time. In most cases, it cannot effectively prevent collapse disasters. Disaster-causing tragedies happen from time to time

The invention discloses a dangerous rock masses collapse damage pre-alarming instrument and pre-alarming method thereof, the stress acquisition device of pre-alarming instrument includes at least twostress detectors, each stress detector is respectively connected to the signal input end of the data real time analyzing and processing device through stress signal transmission line; the data real time analyzing and processing device process stress signal transmitted from stress detector, calculates the stability coefficient of collapse source dangerous rock masses, and determines safety state oftested object, when the safety state of the tested object comes up to the pre-alarming level, the data real time analyzing and processing device sends control signal to the alarming device, the alarming device sends various alarm signals; the invention is used for real time monitoring dangerous rock collapse and safety states of important bridge, tunnel, underground project and other constructions, and conducts a real-time pre-alarm of disaster.
Description
technical field [0001] The invention relates to the field of disaster monitoring and early warning equipment, in particular to a dangerous rock mass collapse disaster early warning instrument and an early warning method thereof. Background technique [0002] Since our country is a mountainous country, dangerous rock collapse, as a major geological disaster, seriously threatens the safety of the life of mountain residents, traffic arteries and municipal construction in our country. For example, there are more than 4,000 dangerous rocks that are prone to landslides in Chongqing alone in the Three Gorges Reservoir area, with a total of more than 50,000 dangerous rock bodies, threatening the lives and property safety of more than 800,000 people; There are more than 2,000 collapse disasters along the highway; there are more than 3,200 collapse disaster points in the Sichuan section of the Sichuan-Tibet Highway. Nearly a thousand casualties are caused by landslide disasters every...
