Embodiment Construction

[0020] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings:

[0021] Such as figure 1 As shown, the present invention is used for the quasi-rock specimen mold of intermittent double-crack rock triaxial compression test, mainly is made of gland 1, middle frame mold 2, base 5, and middle frame mold 2 is arranged on base 5, and gland 1 is set on the top of the middle frame mold 2. The middle frame mold 2 is composed of two modules with semicircular grooves that are buckled together symmetrically. The side walls of the two modules are respectively symmetrically provided with fixed ears 4, and the fixed ears 4 There are bolts 6 that fix the two modules as a whole, and the middle of the two modules is provided with a rectangular groove 3 that can pass the rectangular steel sheet between the two modules; one end of the rectangular steel sheet There are positioning holes. All parts of the mold are made of metal materials...

Abstract

The invention discloses a rock test piece die for triaxial compression test on an intermittent double-fracture rock. The rock test piece die for the triaxial compression test on the intermittent double-fracture rock comprises a base and a middle frame die arranged on the base, wherein a gland is arranged on the top of the middle frame die; the middle frame die consists of two modules which are symmetrically buckled together and are provided with semicircular slots; fixing lugs are symmetrically arranged on the side walls of the two modules respectively; a bolt for integrally fixing the two modules is sleeved with the fixing lugs in a penetrating manner; rectangular wide slots for enabling a rectangular steel sheet to penetrate through and be positioned between the two modules are formed in the middle parts of the two modules. Compared with the prior art, the rock test piece die has the advantages of simple structure, easiness in machining, convenience in dismounting and mounting and fracture positioning accuracy; the precision and the efficiency for preparing a intermittent fracture rock material test piece.

Description

technical field [0001] The invention relates to a rock-like specimen mold for a triaxial compression test, in particular to a rock-like specimen mold for an intermittent double-crack rock triaxial compression test prefabricated by a true three-dimensional geomechanics model masonry module. Background technique [0002] In the field of rock mechanics, fractured rock is a complex medium often encountered in various rock engineering such as mining, water conservancy, petroleum, and nuclear waste storage. Considering that it is difficult to prefabricate intermittent fractures in real rock materials, by preparing rock-like brittle similar model materials, prefabricating intermittent fractures on the basis of model materials has become the basis for exploring the strength, deformation, failure and crack propagation characteristics of intermittent fracture rock brittle materials. important means. [0003] The research status of relevant molds is as follows: [0004] CN20061004213...
