Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific examples and with reference to the accompanying drawings.

[0040] A comprehensive early warning system for landslide deformation, such as figure 1 As shown, it is mainly composed of landslide deformation monitoring network and comprehensive early warning unit.

[0041] The above-mentioned landslide deformation monitoring network includes two parts: a satellite positioning landslide deformation monitoring network and a landslide monitoring auxiliary network. The satellite positioning landslide deformation monitoring network is composed of 1 satellite positioning reference station and N satellite positioning monitoring stations, and its function is to complete the monitoring of the surface displacement of the monitoring target. The satellite positioning reference station is set at a ...

Abstract

The invention discloses a landslide early warning method and system. The system comprises a landslide deformation monitoring net and a comprehensive early warning unit. The landslide deformation monitoring net is composed of a satellite positioning base station and three or more satellite positioning monitoring stations. The satellite positioning monitoring stations are distributed at different monitoring points of the earth surface of a monitoring target. Each satellite positioning monitoring station is connected with a satellite positioning base station so that RTK positioning and calculating can be realized. The positioning results of all the satellite positioning monitoring stations are all transmitted to the comprehensive early warning unit. By monitoring the target overall posture and precisely calculating the displacement, deformation displacement predicting is realized; by fusing multi-source monitoring information, comprehensive early warning is realized. The system has the advantages of being high in early warning precision, simple in algorithm, easy to obtain and high in practicability, and can meet the actual requirements for landslide deformation early warning.

Description

technical field [0001] The invention relates to the technical field of geological early warning, in particular to a comprehensive early warning method and system for landslide deformation. Background technique [0002] Due to the start of construction of key projects such as hydropower or the influence of factors such as environmental and climate changes, geological disasters such as landslides, ground deformation, earthquakes, and land degradation are becoming more and more serious in China. Landslides, collapses, and land subsidence have become one of the major geological disasters in the mountainous areas of Southwest my country. One of the important measures to actively and effectively prevent landslides and other geological disasters is to conduct long-term observations of hidden danger points such as landslides. Once the hidden landslide point is deformed, if it cannot be monitored and effectively warned in time, it may bring huge economic losses to local residents and...
