Dr. Jun-Jie Wang, the author of this book, was born in Gansu Province of China in 1973. In 1995 and 1998, he got Bachelor and Master degrees of Engineering and Hydraulic Geology respectively at Lanzhou University of E R. China. Dr. Wang got Ph.D of Geotechnical Engineering at Hohai University of P. R. China in 2005. He furthered enterprise postdoctoral research at China Merchants Chongqing Communications Research and Design Institute Co., Ltd. from 2006 to 2009, and finished the postdoctoral work at Logistical Engineering University of E R. China in 2011. Now, Dr. Wang works in National Inland Waterway Regulation Engineering Research Center, Chongqing Jiaotong University, P. R. China as the professor and doctoral supervisor.
Dr. Wang devoted to the researches on mechanism and theory of the hydraulic fracturing and selfhealing of core crack in earth rock-fill dam in the past 10 years. So far, he has published more than 50 academic papers, 20 more of which were published in authoritative international journals such as 'G6otecbnique', 'Geotechnical Engineering','Geotechnical Testing Journal', 'Soil Dynamics and Earthquake Engineering', 'Engineering Geology', 'Dam Engineering', etc., and applied for six invention patents and one utility model patent.Professor Wang has been responsible or involved in more than ten projects funded by Ministry of Science and Technology of E R. China, Ministry of Education of E R. China, etc.
Meanwhile, Dr. Wang obtained valuable scientific research achievements in another four aspects of Geotechnical engineering, i.e. (a) mechanism and theory on soil fracture, (b) mechanism and theory on failure of bank soil slope, (c) theory and application of static and seismic earth pressures under steady seepage conditions, (d) mechanism and analyzing method on the stability of over-length pile in layered soils.
