ABSTRACT

This chapter provides a brief summing-up of the research results achieved and experiences accumulated so as to contribute to the development of new research programs and new prevention and remediation methods. Loess in China is outstanding for its stratigraphical intactness, huge thickness, vast expanse of distribution and metastable geotechnical properties. Structurality and structural strength Loess is outstanding for its structurality which is due to its environment of deposition and the diagenetic process it underwent, its micro-structural features, the existence of soluble salts and the soil matrix suction. In climatic, sedimentation and stratigraphical environment conditions, geomorphological evolution has followed correspondingly unique paths resulting in the formation of loess landslides peculiar to such conditions. Efforts to develop the ‘‘West’’ call for large-scale construction of railways and highways and utilization of underground space in urban areas. In loess regions this inevitably entrains the problem of high cut slopes.
