Embodiment Construction
[0020] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0021] figure 1 It is a flow chart of the land subsidence subdivision and layered monitoring and early warning method provided by the embodiment of the present invention. see figure 1 , land subsidence subdivision layered monitoring and early warning methods include:
[0022] S11. Design the framework structure of the land subsidence zoning and layered early warning index system, and carry out index system screening based on the research results of regional land subsidence.
[0023] The framework structure includes three parts, the target layer, the standard and criterion layer, and the indicator layer.
[0024] Among them, the target layer is to realize the moni...

The invention provides a ground subsidence subdivision and layered monitoring and early warning method and device. The method includes: dividing the land subsidence into units based on the land subsidence zoning and each index factor in the layered early warning index system; setting multiple types of monitoring means in each land subsidence unit, and the multi-type monitoring means include: precise leveling, GNSS and InSAR; classify and optimize multiple types of monitoring methods, and establish a land subsidence information solution model; obtain the data to be monitored, and calculate the stratified subsidence value of each land subsidence unit through the land subsidence information solution model; according to the calculation, The stratified subsidence value of the land subsidence is determined to determine the risk level of land subsidence and to carry out early warning. The land subsidence subdivision layered monitoring and early warning method and device provided by the present invention solve the problem that the existing early warning method cannot realize accurate discrimination of subsidence layers and low-precision early warning, and realize high-precision, real-time land subsidence partitioned, layered monitoring and early warning.
Description
technical field [0001] The invention relates to the technical field of engineering geology, in particular to a method and device for monitoring and early warning of land subsidence by division and layer. Background technique [0002] Land subsidence, as a "slowly changing geological disaster", has the characteristics of long duration, slow generation, wide range of influence, complex genetic mechanism and difficult prevention and control. It has become a global environmental geological problem. With the intensification of land subsidence, its impact on urban planning and economic construction is gradually highlighted, such as inducing ground fissures, causing damage to buildings (structures), and causing loss of use value of land resources within a certain range; reducing ground elevation , resulting in a decline in the defense capabilities of urban flood control facilities, resulting in cracking and damage to underground tunnels, affecting the safe operation of subways and ...
