商品簡介

水力劈裂是一種在巖石或土體中由于水位上升引起裂縫產生或擴展的物理現象。土石壩水力劈裂是一個關系大壩安全的復雜問題。王俊杰編著的《土石壩水力劈裂(英文版)》從水力劈裂的發生條件和機理、判定準則和數值模擬方法三方面研究土石壩水力劈裂問題,并研究了糯扎渡土石壩的抗水力劈裂性能。
《土石壩水力劈裂(英文版)》內容包括:文獻綜述,水力劈裂發生條件和機理,心墻土體的斷裂韌度和抗拉強度、I-Ⅱ復合型斷裂破壞判定準則,水力劈裂判定準則、數值模擬方法和影晌因素。
本書讀者包括水利工程的研究者、設計者和建設者,以及對水利工程研究感興趣的人士。

作者簡介

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.
