Device for measuring true triaxial creep of geotechnical engineering test block

The utility model discloses a device for measuring true triaxial creep of a geotechnical engineering test block. The device comprises a support structure, four confining pressure plates, an upper compression plate and a lower compression plate, wherein a closed cavity for wrapping the test block is formed by the four confining pressure plates, the upper compression plate and the lower compression plate; the four confining pressure plates include two long confining pressure plates and two short confining pressure plates; a rectangular top steel plate and a rectangular bottom steel plate are taken as the upper compression plate and the lower compression plate respectively; the two 'L'-shaped long confining pressure plates, which are bended to outside, are erected on the two adjacent side surfaces of the bottom steel plate; the two 'L'-shaped short confining pressure plates, which are bended to outside, are erected on the left two side surfaces of the bottom steel plate; the bottom ends of the short confining pressure plates are arranged on the bottom steel plate; the top steel plate is erected on the top ends of the long confining pressure plates; the top steel plate clings to the inner side surfaces of the two short confining pressure plates; the support structure is internally and vertically provided with pressure sensors which respectively correspond to the four confining pressure plates, the upper compression plate and the lower compression plate; and each pressure sensor is provided with a grating ruler.
