Abstract

A producing method of an intermittent-filling fracture rock sample model includes following steps: (1) determining proportion scheme of aggregate and a cementing material; (2) according to a test result and a similarity relationship of a filling material, determining physical and mechanical properties of a fracture simulation material; (3) under a water-free condition, blending the fracture simulation material and processing it to obtain a thin sheet mixed material; (4) fixing the thin sheet mixed material plane for simulating the fractures with water-soluble threads into a sample making die; (5) weighing components of a rock similar material according to a proportion ratio and mixing the components uniformly, layeredly pouring the mixed components into the sample die, and coating the interior with a release agent; (6) heating the sample with the sample making die in a heating box; (7) taking out the sample from the die and saturating the sample in a boiling manner; and (8) taking the sample out and naturally air-drying the sample. The producing method is simple in principle, is convenient to carry out, is low in cost, is good in moulding effect and fully considers space position of the rock fracture and the properties of a filling material.

Description

technical field [0001] The invention relates to a method for making a rock sample, especially a method for making a rock sample that can consider the filling conditions of cracks inside the rock mass. Where nature affects. Background technique [0002] The existence of fissures in the rock mass destroys its integrity and continuity, and the strength of the rock mass is much lower than that of the rock. Due to the differences in the geometric shape, filling properties and spatial distribution of the fracture surface, there are obvious differences in the strength and deformation characteristics of the rock mass. [0003] At present, experimental research is an important research method to analyze the deformation and strength characteristics of fractured rock mass. However, considering the complexity of the structure of natural rock samples and the difficulty of sampling, it is generally difficult to study the mechanical deformation characteristics and failure laws of real ro...
