The invention discloses a slope large deformation monitoring system and monitoring method. According to the method, four reference points are selected on a slope surface, and one measurement master base station and three measurement auxiliary base stations are deployed separately; when the slope becomes unstable and slides and collapses, or even evolves into mudslide, a paste type smart stone moves with the slope, a distance between a smart label on the paste type smart stone and the base station changes, an instantaneous three-dimensional position of the paste type smart stone is calculated based on an ultra-wideband communication theory by measuring time of signal transmission between the base station and the smart label, and large deformation evolution of slope sliding is evaluated according to displacement change of the paste type smart stone and an early warning is issued. The method solves problems of slope large deformation monitoring and early warning in field. The system can monitor slope instability as well as collapse and sliding, can monitor the whole long-distance movement after collapse, can issue an early warning for roadbed slopes like highways and railways, and hasoutstanding advantages of no wiring, easy operation and stable performance.
Description
technical field [0001] The invention relates to the technical field of slope measurement, in particular to a large deformation monitoring system and a monitoring method for a slope. Background technique [0002] Slope sliding is a progressive cumulative development process in which local failure gradually expands and penetrates to form a sliding surface. When the slope is close to instability and failure, it presents a highly abrupt, random, and discrete nature, and the soil and stones collapse rapidly after the instability and sliding. Fall, that is, when the slope is damaged, the soil and rock will move for a certain distance, which will block roads and railways, bury buildings, farmland and rivers, etc., seriously affecting the transportation hub and endangering the safety of people's lives and properties. Therefore, the middle of the slope It is particularly important to monitor the large deformation in the later stage, especially the large deformation of the slope insta...
