The invention relates to the technical field of geotechnical engineering testing, in particular to a cohesionless soil repose angle measuring method and testing device.The cohesionless soil repose angle measuring method comprises the steps that a leveling assembly is adjusted to enable a base to be in a horizontal state; placing a sample container on the base, wherein the bottom of the sample container is open and is opposite to the top surface of the base; placing a cohesionless soil sample with a preset weight and a preset volume in the sample container; the sample container is lifted upwards, the cohesionless soil sample flows out of the sample container through the opening, and a conical accumulation body is formed on the base; obtaining the weight of the accumulation body; the repose angle of the cohesionless soil sample is calculated according to the weight of the accumulation body, the preset weight and the preset volume of the cohesionless soil sample and the radius of the bottom face of the accumulat
