This database includes slope, aspect and digital elevation model (DEM) data of Qinghai Tibet Plateau. The data comes from the 30m * 30m resolution numerical elevation model data downloaded from the geospatial data cloud website. Using the surface analysis function of ArcGIS software, the slope and aspect information of the Qinghai Tibet Plateau are extracted. The data has been rechecked and reviewed by many people, and its data integrity, position accuracy and attribute accuracy meet the standards, with excellent and reliable quality. As one of the engineering geological conditions, this data is the basic data for the research on the development law of major engineering disturbance disasters and major natural disasters in the Qinghai Tibet Plateau and the analysis of susceptibility, risk and risk.

This data is the disturbance disaster data of 1:250000 major projects in the Qinghai Tibet Plateau. For the scope of disaster interpretation, line engineering (national highway, high-speed, railway and Power Grid Engineering) and hydropower engineering are bounded by the first watershed on both sides of the project; Mine, oilfield and port projects are bounded by 1km away from the project. Engineering disturbance disasters can be divided into two categories: ① landslide, collapse and debris flow disasters induced by engineering construction; ② For natural disasters that may affect the project, it is stipulated that all natural disasters within the above interpretation scope belong to category ② engineering disturbance disasters. The data includes the location, length, width, height difference, distribution elevation, genetic type, inducing factors, occurrence time, lithology and other elements of landslide, disaster related projects and project construction years. Based on Google Earth image and 1:500000 geological diagram, 6176 disaster points were interpreted; Google Earth is mainly used for disturbance disaster interpretation, and combined with field investigation to verify the interpretation results, ArcGIS is used to generate disaster distribution map; The data comes from Google Earth high-resolution images, with high accuracy of original data. In the process of generating disaster files, the interpretation specifications are strictly followed, and special personnel are assigned to review, so the data quality is reliable; Based on the collected data, the disaster risk analysis of the study area can be carried out to provide theoretical guidance for the smooth operation of the built projects and the construction of the line projects not built / under construction.

The types and distribution data sets of major projects in the Qinghai Tibet Plateau mainly include major hydropower projects, major road projects, major mining projects, major port projects and oil field projects. Among them, road projects include national highway, high-speed, railway and power grid projects, and hydropower projects are mainly the project point documents of hydropower station dam site. The data is obtained through data collection and remote sensing image interpretation. The main attributes of the project data are project naming (naming method is project type - project name - project construction year, in which the naming method of hydropower project is project type - watershed name - project name - Project storage year), project construction year, related projects and other characteristics. The data has been checked and modified for many times, and the quality is reliable.

The data is based on the 1:500000 geological map of the Qinghai Tibet Plateau, Refer to the national standard engineering rock mass classification standard (gb50218-2014) rock saturated uniaxial compressive strength UCS and its corresponding representative rocks are divided into five categories: hard rock group, harder rock group, weaker rock group, weak rock group and loose rock group. Engineering geological rock group is the main material component of rock and soil mass, the basis of engineering design, the necessary condition for evaluating the engineering stability of rock and soil mass, and can be used as The evaluation factor of disaster risk analysis avoids the difficulty of risk evaluation caused by too many lithology types, and can be applied to major engineering construction and disaster risk analysis in the Qinghai Tibet Plateau in the future.
