Abstract

The invention relates to a layering and in-situ monitoring device and method for ground subsidence. The layering and in-situ monitoring device comprises a descending device, a sensor probe and a monitoring instrument, wherein the descending device is used for bearing the sensor probe and reaching positions of different rock layers; the sensor probe is connected with the monitoring instrument by a cable and is used for detecting different rock layers from bottom to top and send signals back to the monitoring instrument; the monitoring instrument is used for controlling the action of the descending device, receiving the signals sent back by the sensor probe and recording the dip-angle value of the current position of the sensor probe and the height of the sensor probe rising from the bottom part according to the received signals. The layering and in-situ monitoring device has the beneficial effects that layering and automatic monitoring for the ground subsidence is realized by utilizing a drilled hole.

Description

technical field [0001] The invention relates to the technical field of electronic monitoring, in particular to an in-situ monitoring device and a monitoring method for ground subsidence stratification. Background technique [0002] At present, more than 50 cities in my country have experienced land subsidence disasters, accounting for the most in the world. my country's land subsidence monitoring focuses on the Yangtze River Delta, North China Plain and Fenwei Basin. At present, my country's regional land subsidence monitoring technology is mainly based on InSAR, GPS, geodetic leveling and other methods. InSAR can sensitively monitor changes in land subsidence. However, since land subsidence usually spans several years, it is subject to time decoherence and Restricted by factors such as atmospheric influences. However, GPS, geodetic leveling, etc. are affected by equipment and monitoring by factors such as the skill and professionalism of operators. In point monitoring, bedr...
