Abstract

A method for constructing a physical model of complex fractured rock body of a crack opening and filling type includes collecting occurrence, trace length and spacing parameters of rock body fracturesto obtain statistical result of each group of fractures, and obtaining physical model of complex fractured rock body with open and filled fractures; performing modeling to generate complex fracture network numerical model; setting fracture thickness, pruning the model and reducing the scale to generate complex fracture network solid model; printing a physical model of a complex fracture network with a 3D printer; internally arranging a physical model of that complex fracture network in a sample preparation die, pouring mortar and carrying out cure to prepare a physical model of the complex fracture rock mass containing a fracture material; immersing the physical model of complex fractured rock mass with fractured material in a chemical solvent and vibrating the model in small amplitude until the fractured material dissolves completely, and obtaining the physical model of complex fractured rock mass with fractured opening; heating paraffin wax melting, pouring melting paraffin wax thefractured open complex fractured rock mass physical model, and obtaining a fractured filling complex fractured rock mass physical model through preparation.

Description

technical field [0001] The invention relates to the field of rock mechanics, in particular to a method for constructing a physical model of a crack opening type and a filling type complex crack rock mass. Background technique [0002] In terms of laboratory research on rock mechanical properties, limited by complex model modeling methods, current research is mostly on rock or rock-like (gypsum, concrete) materials, and research on the mechanical behavior of similar rock materials with complex crack distribution is relatively limited. few. With the rise and progress of 3D printing technology, solid modeling of complex structures has gradually become possible. At present, 3D printing technology is widely used in medicine, machinery manufacturing, automobile and other fields, but it is less applied in rock mechanics, especially the application results in geometric modeling of complex structural surfaces are rarely reported. Since the actual rock mass is rich in a large number...
