Abstract

The invention provides a high slope deformation monitoring method and system. The method comprises the steps of eliminating a carrier observation value gross error, eliminating a residual error by using an unbiased estimation method, calculating single-difference geometrical distance, performing carrier single-difference calculation on each monitoring station relative to a base station, establishing a carrier single-difference expression of all synchronous observation satellites, obtaining a difference between carrier single-difference matrixes of two adjacent epochs, establishing a matrix equation of a base line vector variation and a single-difference receiver clock difference variation between the epochs, and calculating a high slope three-dimensional deformation quantity by using a least square method. The monitoring method greatly improves the monitoring efficiency and the monitoring precision; a GPS receiver is arranged at each of the base station and the monitoring stations, and monitoring data of each monitoring station is transmitted to the base station by a switch via an LXI discovery mechanism based on a TCP / IP communication protocol, so that the accuracy of the monitoring data is not influenced by the environment, misinformation, erroneous transmission and the like are avoided, the environmental adaptability is improved, and the monitoring precision is also improved.

Description

technical field [0001] The invention relates to the field of geological disaster engineering and is used for high slope monitoring and early warning, in particular to a high slope deformation monitoring method and system. Background technique [0002] Soil slopes with a height greater than 20m but less than 100m, and rock slopes with a height greater than 30m but less than 100m are high slopes. my country's terrain and geological factors are complex, so that the country's economic development and people's daily life are often threatened by high slopes. The Guanling landslide in Guizhou, the landslide in Chengkou County, Chongqing, and the landslide in Wangong Township, Hanyuan all caused varying degrees of casualties and property losses; during the construction of roads, railways, and large-scale hydropower projects, high-slope landslides will hinder the progress of construction , delay the construction period, bring economic losses, and even threaten the lives of construct...
