The invention discloses a coarse-particle soil expansion test device which comprises a fixing frame, a pressurizing lever, a soaking tank, a dial indicator, an expansion assembly and a displacement transmission assembly, and the ratio of the side area of the sample to the pressure-bearing area of the sample is 0.97-1.46. The invention further provides a coarse-particle soil expansion test system which comprises a computer system and the coarse-particle soil expansion test device. The invention also provides a coarse-particle soil expansion test method which is realized by the coarse-particle soil expansion test device. By adopting the technical scheme, according to the coarse particle soil expansion test device, system and method disclosed by the invention, the ratio of the side area of the sample to the pressure-bearing area of the sample is set in a range of 0.97-1.46, and a relatively accurate expansion rate value can be obtained. 本发明公开了一种粗颗粒土膨胀试验装置，包括固定架、加压杠杆、浸水槽、百分表、膨胀组件以及位移传递组件；试样的侧面积与试样的承压面积之比为0.97~1.4
