摘要
设计了室内突水、涌砂试验装置，以弱胶结砂岩为试样，在各不同的初始压力下，模拟突水、涌砂过程，由此总结出突水、涌砂与各影响因素间的关系；给出了各试样发生突水的临界水头梯度；分析了突水机理；最后指出了试验中的不足之处。
Water and soil outburst model was designed. The test with different samples wasdone at the fixed press. The relation between water outburst and influence factors,the critical hydraulic gradient of water outburst and water outburst machinism in the test conditionare obtained.
