Abstract: This paper is a briefness introduction of the monograph, "Urban Engineering Geology for the Rock and Soil Foundation" which we finished recently .the study of urban erigineering,geology for the rock and soil foundation is the crystallization of synthesis, comprehensive and sublimation of many subjects(i. e.,engineering geology, geotechnical engineering, science of engineering rock and soil, environmental engineering, etc.)in the urban tract. Theoretical system of urban engineering geology for the rock and soil foundation is analysed, the contents of the study of urban engineering geology for the rock and soil foundation are studied, the basic methods of urban engineering ,geology for the rock and soil foundation are also discussed in this thesis.
