导语摘要
天然岩石通常包括许多不同种类的缺陷，如裂隙、节理、弱面等，这些缺陷对岩石材料的强度、变形及其裂纹扩展特征有着重要的影响。为了深入理解断续结构岩体的破坏机理，《断续裂隙岩石材料强度破坏与裂纹演化特性（英文版）》采用试验和数值方法，系统研究了含不同预制裂隙分布(包括：单裂隙、双裂隙、叁裂隙以及混合缺陷)的脆性岩石强度、变形及其裂纹扩展特性。
作者简介
Dr. Sheng-Qi Yang was born in December 1978. In 2003, he started his Ph.D. research, in Hohai University,Nanjing, PR China, and got Geotechnical Engineering of Doctor s degree in April 2006. In 2007-2008, he continued his postdoctoral work in Ecole Polytechnique de Paris, France. In 2014-2015, he obtained an Endeavour Research Fellowship in Australia and commenced his research in the Department of Civil Engineering, Monash University, as a visiting professor.From 2012, he has been promoted as a full-time professor and a Ph.D. supervisor in China University of Mining and Technology. In March, 2014, he was elected as an assistant director of State Key Laboratory for Geomechanics and Deep Underground Engineering. In 2013, he was awarded the Program for New Century Excellent Talents in University from Ministry of Education. He obtained the Youth Science and Technology Award from Chinese Society for Rock Mechanics and Engineering and Sunyueqi Foundation Council. In 2011, he also obtained the Second Prize of Science and Technology Progress from Ministry of Education. In the past 5 years,he took charge of more than ten key scientific projects including three projects from National Natural Science Foundation of China (NSFC). His research interests focus mainly on deep-fissured and jointed rock mechanics; rock creep (time-dependent) experimental and model mechanics; and deep underground rock mass engineering and reinforced technique.
