Intelligent landslide catastrophe monitoring method based on L-type liquid metal antennas

Abstract

The invention discloses an intelligent landslide catastrophe monitoring method based on L-type liquid metal antennas. The intelligent landslide catastrophe monitoring method based on the L-type liquid metal antennas includes the following steps that first, a certain number of L-type liquid metal antennas are arranged in a landslide body to be monitored; second, the natural frequency of the L-type liquid metal antennas is measured; third, data of the natural frequency of the L-type liquid metal antennas are transmitted; fourth, the data are analyzed and a landslide alarm is given out. The intelligent landslide catastrophe monitoring method based on the L-type liquid metal antennas has the advantages that the anti-interference capacity of a circuit, the automation degree and the measurement precision are high, and the changes of the state of the landslide can be remotely monitored in real time.

Description

technical field [0001] The invention belongs to the technical field of geological disaster prevention and control, and in particular relates to an intelligent monitoring method for landslide catastrophe. Background technique [0002] my country is a country with extremely complex terrain and landforms, and it is also a mountainous country, especially in the southwest of my country and Fujian, Guangxi, Guangdong and Hainan along the southeast coast. In the past few hundred years, there have been many large-scale landslide events. With the development of the national economy, a large number of facilities such as railways, highways, water conservancy, mines and towns are built, especially in the construction of hills and mountainous areas. The number of slopes excavated and filled in human engineering activities will increase, and the height will increase. getting bigger. Geological disasters such as side slopes and landslides have caused huge economic losses and heavy casual...

Problems solved by technology

For the internal inclination monitoring of landslides, borehole inclinometers are mostly used. Borehole inclinometer monitoring is to use inclinometers to measure the slope of boreholes section by section at regular intervals, so as to obtain the internal horizontal displacement of rock and soil and the principle of time-varying changes. The principle of the position observation method is to measure the arc angle change based on the vertical line according to the influence of the pendulum by gravity. The probe cannot pass through and the monitoring is scrapped

For internal relative displacement monitoring, when the landslide is deformed, the relative position between two points inside the slide body will change. Instruments can be installed to measure the relative displacement or relative settlement between two points in the slope body, but it is usually only applicable to the sliding surface and the sliding body Relatively steep rock landslides are less suitable for soil landslides
