Introduction

To standardize the investigation and evaluation of geological disasters, and guide the development of the 1.50000 geological disaster investigation work in the national geological disaster-prone area. Set this standard. For more than 20 years, China has carried out a 1.500000 environmental geological survey, large rivers and important traffic in the country. Special investigations on geological disasters along the line, especially the county (city) geological disaster investigation and zoning work covering the mountainous and hilly areas of the country. Initially found out the distribution of geological disasters in China, divided the geological disaster-prone areas and dangerous areas, and established a group monitoring and prevention system to effectively alleviate Loss of geological disasters. However, with the rapid development of China's social economy, landslides, collapses, mudslides, etc. are intensifying, seriously damaging the people. For the safety of life and property and the sustainable development of the social economy, there is an urgent need for more systematic, accurate, and accurate survey data. According to the "Regulations on Prevention and Control of Geological Disasters" issued by the State Council and the "Decision of the State Council on Strengthening Prevention and Control of Geological Disasters", The country carried out a 1.50000 geological disaster investigation, providing a basis for governments at all levels to formulate geological disaster prevention planning and implement geological disaster warning projects. Basis. Specification for investigation of landslide collapse debris flow disaster (1.50000)

1 Scope

This standard specifies the content, control accuracy, basic methods and results of the landslide, collapse, and debris flow hazard investigation (1.50000). Acceptance and other requirements. This standard applies to regional investigations of three types of geological disasters such as landslides, collapses and debris flows.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Landslide landslide The geological body slides down the geological weak face under the action of gravity. Landslide usually has a double meaning, gravity sliding process, or weight Force sliding geological bodies and accumulations. 3.2 Collapse rockfal Under the action of gravity, the geological body suddenly accelerates to collapse, roll or jump from the high steep slope, with obvious breaking or overturning. 3.3 Debris flow debrisflow A kind of mud, sand, stone and other solids in the mountain valley or slope surface under the action of natural and human factors such as rainfall, melting ice and breaking the bank. The fluid of matter. 3.4 Slope naturalslope A natural slope formed by various geological processes with high elevations on the terrain, such as hillsides, coasts, river banks, etc. 3.5 Unstable slope unstableslope A slope with deformation characteristics or trends such as creep, collapse, dumping or lateral cracking. 3.6 Dangerous rock massangerous rocksmass A geological body that is cut and separated by multiple sets of discontinuous structural surfaces and has poor stability and may collapse in the form of dumping, falling or collapsing. 3.7 Deformable deformablerockmassorsoilmass Geological separations that do not form clear slip or collapse due to gravity are easily converted into landslides or collapses under artificial disturbances such as excavation.
