【摘要】 在深入研究断层垂向封闭机理的基础上，建立了断层垂向封闭的三种地质模式，并利用断层面压力、断移地层的砂泥比值和断层填充物与围岩声波时差的相对关系，分别研究了三种不同地质条件下的断层垂向封闭性。实例应用表明，这些方法用于研究断层垂向封闭性是可行的。更多还原

【Abstract】 Based on in depth study on vertical confining mechanism of fault, three geological models were developed, followed by analyzing the vertical confining properties of fault in three different geological conditions by using pressure exerted on fault surface, the ratio between sandstone and mudstone in faulted strata, and difference of interval transit time between filling material of fault and surrounding rock. It was indicated from actural application that these methods are feasible and practicable for these studies.更多还原
