Abstract

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 of different parts of the rock cannot be observed are solved.

Description

technical field [0001] The invention relates to the technical field of rock mechanical performance detection, in particular to a device for observing the deformation of rocks in the whole field under seepage conditions. Background technique [0002] Before the implementation of large-scale civil engineering projects such as tunnels, underground roadways, and hydropower dams, it is necessary to study the mechanical properties of the rock where the project is located. Since most rocks are in the environment affected by groundwater, it is usually necessary to observe the deformation of rocks under seepage conditions in the process of studying rock mechanical properties. [0003] At present, the way to observe the deformation of rock under the condition of permeability is to use extensometer observation. The extensometer consists of three parts: sensor, amplifier and recorder. When the extensometer is used for measurement, the sensor is in direct contact with the rock specimen...
