Landslide deep displacement real-time monitoring system and method based on stay wire posture interpreting

Abstract

The invention relates to a landslide deep displacement real-time monitoring system based on stay wire posture interpreting to solve problems existing in the prior monitoring art.A monitoring hole is used as a measuring line, deformation of rock and soil mass in the monitoring hole is transmitted to the stay wire through annular node terminals distributed in an array mode, and at the moment, the two ends of the stay wire penetrating through the node terminals deflect with a fixed pulley at the node terminals as the center; inductors at the two ends of the node terminals will capture changes of the stay wire posture and transmit the information to the stay wire through an electric brush pulley, and the change of the stay wire posture is transmitted to an earth surface monitoring control terminal through the stay wire; all the node terminals are connected through a data transmission technology, the positions, in the measuring line direction, of the node terminals are inverted through signal transmission time difference, displacement perpendicular to the measuring line direction is inverted through posture information of the stay wire, and therefore displacement of the rock and soil mass on the measuring line is monitored.

Description

technical field [0001] The invention relates to a method and a system device for real-time monitoring of deep displacement of landslides, in particular to a recyclable real-time monitoring system that can meet the large deformation monitoring requirements on the measuring line. Background technique [0002] Landslides are one of the major geological disasters worldwide, often causing casualties, road burial, and house damage, seriously threatening the safety of life and property. Monitoring and early warning, as one of the important measures to mitigate the risk of geological disasters, is getting more and more attention. The occurrence, development and evolution of landslides is accompanied by changes in a large number of macroscopically measurable physical information, such as surface displacement, deep displacement, surface inclination, rock and soil mass pressure, and acoustic emission. Among the many measurable physical quantities, the surface displacement and deep dis...

AI Technical Summary

Problems solved by technology

The application of TDR technology monitoring can quickly collect digital measurement results and transmit them to the receiving end, so as to realize the intelligence of landslide monitoring, but it cannot be used to monitor areas where there is only inclination but no shearing action, and the direction of landslide movement cannot be determined

In addition, due to the limitation of deformation coupling conditions, its embedding method has yet to be studied and has not been widely used.
