%X In 2019, acoustic response experiments were conducted on frozen soil under temperature change conditions in Mohe and Dongying, studying the longitudinal wave velocity variation of frozen soil under temperature change conditions (-25 º C~25 º C). Observation elements include length, density, temperature, sound wave velocity, etc. The data resource collection time range is from September 20, 2019 to October 20, 2019. The acoustic detection system is used to measure the propagation speed of transverse and longitudinal waves in frozen soil layers at different burial depths and temperatures. Used to establish a model of the influence of frozen soil layer temperature on longitudinal wave velocity.
