[0014] Below in conjunction with example the present invention is further described. Example 1: In the drilling and blasting excavation project of underground engineering, 5-6 miniature landslide predictors are used to find tiny cracks near the working surface (the part that has been excavated and not yet covered with lining, the area with high incidence of landslides), the roof of the cave and the side wall outlets Dispersed arrangement and installation in several places where cracks are more typical. When the cracks accelerate to expand, the forecaster detects and sends out lights and alarms, and the construction team immediately withdraws from the work surface to avoid accidents caused by landslides and injuries. Geotechnical engineers and safety engineers went to the scene to further judge the danger and formulate a plan to strengthen the surrounding rock. After the surrounding rock in this section is stabilized (or covered with lining), the micro landslide forecaster can...

Abstract

The invention provides a micro landslides prediction instrument. The micro landslides prediction instrument is characterized in that the change of surrounding rock and the development of fracture are continuously monitored through a resistance strain gauge, and the acceleration change characteristic of the surrounding rock instability is sensitively and effectively determined according to the acceleration change of the resistance value, so as to provide a forecast warning for landslides. According to the micro landslides prediction instrument, the landslides prediction technology which is simple, easy to be performed, small in cost, unattended and monitors all the times is provided, which can be applied to the prediction of landslides of underground engineering, safety pre-warning for earthquake proofing and emergency rescuing, and the collapsing prediction of mine, dangerous rock, side slope, dam and the like.

Description

technical field [0001] The invention belongs to the technical field of civil engineering safety, and relates to underground engineering collapse prediction, earthquake resistance and emergency safety early warning, mine, dangerous rock and side slope collapse prediction. Background technique [0002] At present, landslide prediction relies on a large amount of measurement data and complex analysis. The operation is complicated, and the measurement affects the construction of the construction work surface. The timeliness is poor, the cost is high, the prediction accuracy is not high, and it is impossible to achieve real-time prediction and timely avoidance. Lack of use value. At present, there is no invention of a finished landslide forecasting instrument available for use, nor is there a very mature forecasting technology. It is often a large-scale project that establishes a set of expensive and complex measurement systems, which are operated by a professional high-skilled ...
