摘　　要：为了研究连续介质的流固耦合作用,在推导岩体力学和流体力学相似条件的基础上,确定了流固耦合相似模拟的准则,研制的以石蜡为胶凝剂的流固相似模拟实验材料,其耦合参数与原型相似,性质满足流固耦合相似模拟实验要求。通过神府矿区某矿1-2煤层开采的流固耦合相似模拟实验,研究结果表明:模拟所得出的采煤工作面上覆岩层的运动破坏及裂隙演化规律与现场一致,潜水渗流规律和其它参数也与原型相似。证明了实验材料的选取正确和耦合参数的确定合理。In order to study the continuous medium coupling equation,the simulation conditions of rock mechanics and fluid mechanics are inferred,and the liquid-solid coupling simulation criterion is defined.The liquid-solid-coupling simulation experiment materials has been researched,paraffin wax is used as condense material.The coupling parameter is similar to the prototypes of rock and the properties meets to the requirement of liquid-solid-coupling simulation experiment.According to the liquid-solid-coupling simulation experiment of 1-2 coal mining in Yu-Shen-Fu mining area,it indicated the rock＇s movement and destroy and the fracture＇s evolution is consistency between simulation materials experiment and field observation,the flow law and other parameters are similar to the prototypes of rock,this make further reliability on the selection of simulation materials and parameter are reasonable.
