A method of landslide monitoring

Abstract

The invention discloses a landslide monitoring method, and belongs to the field of geological disaster monitoring. The method is characterized by comprising the steps of: A, drilling a hole in a landslide mass; B, determining the length of a required button type landslide monitoring device; C, taking out a cylindrical framework, removing electric power storages, transmitters, and resistance readers on remaining cylindrical frameworks, sequentially connecting line butt joints in series, and finally tightening with the butt end of a screw of a spare cylindrical framework; D, arranging the buttontype landslide monitoring device into the drilled hole, and filling the drilled hole with dry sand body; E, connecting a solar cell panel to the electric power storage; and F, when the landslide massis displaced, a convex metal block pressing an ITO conductive glass; the ITO conductive glass being broken so that a transmission loop is powered off; and a receiver losing signals and generating early warning. According to the landslide monitoring method, the whole monitoring method is simple and easy to operate; the method that the landslide mass is slightly displaced so that the landslide monitoring device is pressed to generate early warning is adopted; the monitoring accuracy can be effectively improved; the early warning effect is good; and the applicability is high.

Description

technical field [0001] The invention relates to the technical field of geological disaster monitoring, in particular to a landslide monitoring method. Background technique [0002] my country is a mountainous country. According to data, the area of ​​mountains, hills and plateaus accounts for more than 60% of the total land area. The mountainous characteristics have resulted in frequent occurrence of geological disasters, the most common being landslide disasters. Therefore, it is particularly important to monitor and prevent slope stability. It is of great economic value to establish a set of monitoring devices and monitoring methods for slope landslides. Conventional monitoring methods include: visual observation of cracks and physical dumping deformation; measurement by theodolite, rangefinder, etc.; monitoring of slopes by GPS measurement and infrasound technology and other monitoring methods. In the traditional measurement method, a lot of manpower and material resou...

Problems solved by technology

[0005] The existing technology represented by the above-mentioned patent documents has the following defects: it fails to take into account that for slopes with a deep sliding interface, the slope surface has a high probability of overall displacement in the early sliding, but the surface of the slope is far away from cracks. It is very likely that the sliding of the slope cannot be found in a small area, so early warning cannot be given; it is neglected that the sliding of the slope is often large-scale, and it is very important to distinguish the sliding soil from the non-slip The judgment of sliding soil has great uncertainty, and it is necessary to locate the sliding boundary line in the early stage, which is very difficult and poor in applicability
