Along with the implementation of China's strategy of globalization， the promotion of "the Silk Road Economic Belt and the 21st-Century Maritime Silk Road" project， and the continuous intemationalization ofitems construction， a number of professional staff majored in engineering geology and related technical have gone aboard to engage in transnational projects. To adapt to the new international environment， a new generation of engineering geology professionals have to be trained by the universities， researching institutes and domestic multinational enterprises. As English is the language used most widely in the world， it is necessary for us to master the common and specialized English. In view of this， the author has written the Engineering Geology after three-year efForts.
　　This book mainly focuses on the basic knowledge of engineering geology， with nine chapters. In chapter 1 the development history， the research scope and the branches of engineering geology are introduced. Chapter 2 and chapter 3 are about the definition， classification， properties of three types of rocks， including igneous rocks， sedimentary rocks and metamorphic rocks， based on the general rock minerals. In chapter 4， it introduces the geological actions of weathering， slope， fiuvial geology and wind. As for chapter 5， geological structures are mentioned detailedly， such as the folds， faults， and the discontinuity ofjoints and fissures. In chapter 6， the main object of engineering construction-soil， is introduced， and the formation of soil and the main properties of soil are analyzed briefly. The definitions， circulations and main issues of groundwater are discussed in chapter 7. The types， inducing factors and preventive measures of mass wasting are introduced in the next chapter. The book ends on the discussion of the common natural disaster-earthquake.
　　This book can be the teaching materials or the extracurricular reading book for undergraduate and graduate students， majored in geological engineering， geotechnical engineering， hydraulic engineering， civil engineering， etc. And it also is the reference book for the professional staff， management personnel and teachers， who engaged in work related to geological engineering.
