Device of observing rock full-field deformation under seepage condition

The invention relates to the technical field of rock mechanical-property detection, and particularly to a device of observing rock full-field deformation under a seepage condition. The device includesa photographing mechanism, a pressing mechanism and a first pump machine. The first pump machine cooperates with a rock test piece, and injects permeation water into the rock test piece. The pressingmechanism has a pressing portion. Compression cooperation is between the pressing portion and the rock test piece. The device has the advantages that a structure is simple and compact, assembly is easy, and costs are lower; at the same time, test data obtained by measurement are accurate and reliable; and in addition, a visualization manner is used in combination with an image analysis method, deformation of the rock test piece can be measured more accurately, and the problems that when an extensometer is used for observing deformation of rock under the seepage condition, an observation areais limited, and deformation
