摘要:
水压爆破是一种使岩石破碎更为均匀的科学高效的爆破方法.水压爆破岩石的整个过程可细分为四个部分:水中冲击波的形成及传播、冲击波在水和岩石界面上的反射和透射、应力波在岩体中的传递及衰减、应力波的作用造成岩石破裂.通过对水压爆破整个过程的理论分析,得到了冲击波在水中的传播规律、孔壁处冲击压力和与不耦合系数的关系、岩石质点位移随质点距爆心距离的变化规律以及岩石在应力波作用下的破裂机理和破裂区的范围,这些规律将为后期的试验研究和数值分析研究提供参考.
Abstract:
The water pressure blasting is a kind of scientific and effective blasting method that makes the rock broken more uniform. In this paper, the whole process of the water pressure blasting was subdivided into four parts: the formation and spread of shock wave in water, the reflection and transmission of shock waves in the water and rock interface, the transmission and attenuation of stress wave in rock mass, and the effect of stress wave causing rock burst. The rule of each process is analyzed in theory. Moreover, the propagation law is acquired of shock wave in water, the relation of shock wave pressure and no coupling coefficient in hole wall, the law of rock particle displacement with the distance from blasting center and the zone of rock failure. The rule provides reference for later experiment research and numerical analysis study.
