Abstract

Risk management is a new branch of management science. Risk investigation is the basis of risk identification, analysis, evaluation and treatment. This paper discusses the progress in geohazard risk management in China and abroad and their differences and puts forward the unified opinions of the terminology of geohazard risk management in China. It deals with the types and accuracies of geohazard risk investigation, risk classification, content and methods for risk investigations at different accuracies and technical requirements for risk investigation. Take for example the risk investigations of the urban area of Yan’an City and Hutoumao site, Shaanxi, the paper separately describes the process and results of geohazard risk investigations and zoning at scales of 1:10,000 and 1:1000.
