Thinking on Effective Methods of Successful Prediction of Geological Hazards in Shaanxi, China

Abstract

In the process of human survival and development, it is inevitable to transform the original state of the world, thus forming a contradiction between the earth and the earth. The violent form of this contradiction is geological disasters. Geological disasters pose a threat to human life and property, and cause damage caused by natural or human factors, often causing casualties. The destruction process of geological disasters is usually a gradual process, showing many pre-disaster symptoms, such as local landslides, surface cracks, building deformation, tree skew, and ground sound. Evacuation can be avoided in advance according to the disaster precursors, so as to avoid casualties and achieve successful prediction. By reviewing the general situation of geological disasters in Shaanxi Province and the casualties in 2020, the difficulties in the prevention and control of geological disasters are summarized. In view of these difficulties, an on-site investigation, visit and analysis of geological disaster points and successful forecast points in Shaanxi Province in 2020 were conducted. In addition, combined with actual cases and years of work experience, the successful prediction experience of geological disasters was discussed from 8 aspects. Finally, the "Regulations on the Reward for Successful Geological Disaster Forecasting in Shaanxi Province" was revised in order to improve the successful prediction ability of geological disasters in Shaanxi Province and even the whole country, provide reference for future prevention and control of geological disasters, and effectively protect the safety of people's lives and property.

Geotechnical Deformation Distributed Measuring Technology Research Based on Parallel Spiral Sensing Line

“…The current measurement of geotechnical deformation in the world mainly includes total station observation technology [ 6 , 7 , 8 ], GPS navigation satellite positioning technology [ 9 , 10 , 11 ], remote sensing technology [ 12 , 13 , 14 ], pull-wire displacement sensing technology [ 15 , 16 ], fiber optic sensing technology [ 17 , 18 , 19 , 20 ], coaxial cable sensing technology [ 21 , 22 , 23 ], computer vision techniques and numerical simulation techniques [ 24 , 25 ], etc. The total station is a three-dimensional coordinate measurement system consisting of three main components: an optical distance meter, an electronic longitude and latitude meter, and an automatic data recording device.…”
