AB  - The data obtained from the simulation experiments of identifying the acoustic characteristics of shallow geological hazards conducted in Beijing in 2017 and 2018 includes observation elements such as pressure, porosity, density, and acoustic velocity. This data element includes shallow gas, shallow water flow, and natural gas hydrates. Shallow gas contains: shallow gas pressure, longitudinal wave velocity, confining pressure, density, porosity, and particle size; In shallow water flow, there are: shallow water flow pressure, longitudinal wave velocity, confining pressure, density, porosity, and particle size; Natural gas hydrates contain: saltwater saturation, hydrate sample length, hydrate conversion rate, hydrate saturation, longitudinal wave velocity, temperature, and pressure. The data resource collection time range is from June 1, 2017 to December 30, 2018. The acoustic detection system is used to measure the propagation speed of longitudinal waves in normal formations, shallow gas of different pressure levels, and natural gas hydrates of different saturation levels to establish a shallow geological hazard acoustic prediction model.
