摘要
A bidirectional variable cross-section water-pressure bearer cycle test system for a coal mine water inrush model test, comprising a water-pressure loading portion and a water-pressure bearer portion, wherein the water-pressure loading portion is composed of a water supply tank, a loading water pump, a water piezometer, a water control valve, a water inlet pipe, a water discharge pipe, etc. in the prior art, and controls the size of a loaded water pressure, so as to achieve the cyclic loading of the water pressure; and the water-pressure bearer portion is composed of a variable cross-section water-pressure bearer assembly and a variable water-level water-pressure bearer assembly, and is set to be formed in an airtight main frame. The variable cross-section water-pressure bearer assembly is composed of a variable cross-section water storage tank, a variable cross-section water baffle and a variable cross-section porous plate, and the variable water-level water-pressure bearer assembly is composed of a variable water-level water storage tank, a variable water-level water baffle and a variable water-level porous plate. According to test requirements, the separate position of the variable cross-section water baffle is designed, and the baffling position of the variable water-level water baffle is determined, so as to achieve the bidirectional variable cross-section water-pressure bearer cycle.
