裂隙岩体爆破理论研究进展

Research Progression in Blasting Theory for Fracture Rock Mass

节理裂隙对岩体爆破效果有很大的影响。本文从裂隙岩体爆破、冲击荷载作用下岩石特性、岩体爆破数值模拟等方面论述、评价了岩体爆破理论的研究现状。在其基础上对节理岩体的质量综合评价、力学模型的研究、数值模拟的研究、理论与试验相结合等方面的发展趋势提出了几点看法。

Cleavage and fracture have a strong impact on blasted result for rock mass. The paper expounds and estimates the status quo of research into rock blasting theory in aspects of blasting fracture rock, rock properties under the shock load, and numerical modelling of rock blasting. Then ,the paper presents the develop trend about the comprehensive estimation of fracture rock, study on dynamic model and numerical modelling,and combining the theory with practice.
