三轴应力状态下单裂隙灾水机理的实验研究

EXPERIMENTAL STUDY ON THE WATER INRUSH MECHANISM IN SINGLE FRACTURE UNDER TRI-AXIAL STRESS STATE

摘要: 介绍了单裂隙试样在不同三轴应力状态下,其导水性能的变化规律,充填物对裂隙导水性的影响,并得出了突水判据。

Abstract: The variation regularity of the water-transmitting property in single fracture sample under triaxial stress state, and the influences of fillings on the water-transmitting property of fracture are introduced. The criteria of water inrush are obtained.
