一种离层上位岩层破断时离层水动水压力变化过程模拟方法

本发明涉及一种离层上位岩层破断时离层水动水压力变化过程模拟方法，属于离层水动水压领域，解决了离层水动水压力难以原位监测、无法准确评估岩层破断时离层水动水压的问题。本发明通过向离层腔内部充水模拟离层积水，向液压腔内部充水模拟离层上位岩层所承受的自重及上覆岩层挤压产生的均布载荷，并通过离层腔水压监测器监测离层腔水体的初始水压及岩板破断时冲击离层腔内水体时的动水压。本发明实现了对离层上位岩层破断并冲击离层水的过程进行模拟，以及对这一过程中产生的离层水动水压力进行监测，可为矿区离层水动水压力大小的评估提供依据，进一步指导矿区离层水害的防治。 The invention relates to a method for simulating a stratifugic water dynamic water pressure changing process when a separation layer upper rock stratum breaks, belongs to the field of stratifugic water dynamic water pressure, and solves the problems that the stratifugic water dynamic water pressure is difficult in in-situ monitoring, and the stratifugic water dynamic water pressure cannot be accurately evaluated when the rock stratum breaks. According to the invention, water is filled into a separation layer cavity, so that separated strata seeper is simulated; water is filled into a hydrauliccavity, so that dead weight borne by the separation layer upper rock stratum and a uniformly distributed load produced by overlying rock stratum extrusion
