Description

technical field [0001] The invention relates to the technical field of disaster early warning, in particular to a wireless monitoring system and method for slope deformation under blasting and excavation of high and steep rock slopes. Background technique [0002] During the construction of expressways in mountainous areas, the terrain undulates greatly, and high and steep cutting slopes are formed on both sides of the road. High and steep rock slopes are unstable during blasting and excavation or after excavation, which poses a certain threat to the personal safety of passing vehicles and on-site construction personnel. [0003] According to the inventor's understanding, the surface displacement before the instability of the high and steep rock slope is small, the slope instability is sudden, and the early warning time is short. In the monitoring stage, due to the blasting and excavation, the construction environment is relatively unsafe, and the monitoring personnel canno...

Rock high and steep slopes are unstable during blasting and excavation or after excavation, which poses a certain threat to the personal safety of passing vehicles and on-site construction personnel

[0003] According to the inventor's understanding, the surface displacement before the instability of the high and steep rock slope is small, the slope instability is sudden, and the early warning time is short. In the monitoring stage, due to the blasting and excavation, the construction environment is relatively unsafe, and the monitoring personnel cannot continuously monitor around the clock, and the warning of the instability disaster of the high and steep rock slope lags behind.

Traditional monitoring methods for high and steep rock slopes require wiring, but the blasting construction will destroy the lines, making it impossible to monitor the deformation of steep rock slopes

The data processing module of the traditional monitoring system simply predicts the value of each monitoring quantity, and only when the value of the monitoring quantity exceeds the threshold value, the alarm will be issued. However, in the actual process, the landslide model collects a large number of stresses, displacements, angles, and accelerations. , groundwater level and other physical quantities, but there are large differences between different physical quantities and are affected by the selection of dimensions. It is difficult to draw different sets of data in the same coordinate system, which is not conducive to the analysis of the change trend of each physical quantity and the mutual influence between them. The influence of the coupling of various physical quantities on slope stability should be considered
