【摘要】 预制裂隙岩石裂纹扩展规律研究是从细观、宏观角度了解和掌握岩石破坏机理的一条重要途径,由此开展的研究拓宽了人们对岩石的已知认识,围绕其开展的相关研究也是目前业内研究的热点和难点之一。在现有研究方法的基础之上,从介绍预制裂隙岩石试样的制备入手,分别对常见岩石及类岩石材料的预制裂隙形式及其适用条件、预制裂隙岩石裂纹扩展规律的常用研究手段及其优缺点、预制裂隙岩石裂纹扩展规律的研究进展等方面进行了详细的介绍,并通过对前人取得的成果进行对比和思考,指出了预制裂隙岩石裂纹扩展规律这一研究领域仍需着力研究的方向。更多还原

【Abstract】 Crack propagation law of pre-fractured rock is a significant way to understand and grasp the failure mechanism of rock. From the micro and macro point of view,relevant research has broadened the existing cognition of rock,and it is one of the hot and difficult spot in rock mechanics research. This review aims to fully describe the forms,applicable conditions, research approach, advantages and shortcomings, crack propagation law of prefractured rock and rock-like sample based on the existing research methods. Finally,some prospects are proposed for later research in crack propagation law of pre-fractured rock.更多还原
