Rock disintegration degree test device and test method in dry-wet alternating environment

The invention provides a rock disintegration degree test device and a rock disintegration degree test method in a dry-wet alternate environment, which belong to the technical field of geotechnical engineering. The rock disintegration degree test device comprises a first container and a second container, wherein the second container is at least partially located below the highest horizontal plane of the first container; the second container at least has a through hole in the part below the highest horizontal plane of the first container, so that the second container is communicated with the first container by means of the through hole; and a rock to be tested can be accommodated in the second container. The rock disintegration degree test method is implemented based on the test device. By applying the rock disintegration degree test device and the rock disintegration degree test method, the disintegration mechanism of the rock can be known simply, conveniently and quickly, the disintegration mechanism is an im
