3D PRINTING-BASED COMPLEX FRACTAL FRACTURE MULTI-COUPLING SEEPAGE EXPERIMENT SYSTEM AND METHOD

摘要

The present invention relates to the technical field of geotechnical engineering, and relates in particular to a 3D printing-based complex fractal fracture multi-coupling seepage experiment system and method. A seepage experiment apparatus uses a 3D printing method to conveniently construct experiment samples of different types or characteristics, so as to satisfy experiment requirements for various types of fractured rock masses. The experiment apparatus is able to measure seepage characteristics of different rock masses by performing experiments with different samples. Water storage depths of water tanks are adjusted to obtain different water pressures for performing experiments on the samples. Experiments may be performed on sample unidirectional or multidirectional seepage characteristics by turning on seepage valves at different positions. The 3D printing-based complex fractal fracture multi-coupling seepage experiment apparatus and method simulate seepage characteristics closer to real intact rock masses, so as to provide theoretical guidance and significance for underground engineering design and construction.
