Abstract: Device and method for measuring true triaxial creep of a geotechnical engineering test block, including a supporting structure; the device includes four confining pressure-plates and upper-and-lower compression-plates forming an enclosed cavity for the test block; confining pressure-plates include two long confining pressure-plates and two short-confining pressure-plates, upper-and-lower compression-plates are rectangular top and bottom steel-plates, two L-shaped long confining pressure-plates bent towards the outer side lapped on two adjacent side faces of the bottom steel-plate, two L-shaped short-confining pressure-plates bent towards the outer side lapped on remaining two-side faces of the bottom steel-plate, and bottom ends of the short-confining pressure-plates are placed on the bottom steel-plate; top ends of long confining pressure-plates lapped on the top steel-plate, and top steel-plate leans against inner side faces of two short-confining pressure-plates; vertically pressure sensors corresponds to four confining pressure-plates and upper-and-lower compression-plates in the supporting structure, and grating shortrulers on pressure sensors.
