The Development of Risk Management Research on the Exploitation of Underground Space in China

China is going to lead the world with respect to the scale and quantify of urban underground space. The necessity and urgency of risk management in underground engineering are determined by its characteristics such as large scale, rapid development and the grim safety situation. The establishment of a risk management system, detailed risk assessment for construction of metro project, and risk control, are very necessary. The present status and issues existing m. risk management for safety operation in underground projects are mainly described, which include technical and management issues. The cognitions about risk management which is achieved in the recent years' are referred, which includes: people are the key to risk management, accidents are foreseeable and can be monitored, particularities of risk management in underground engineering compared with ground engineering, risk management is necessary in the whole period, inapplicability of insurance as a means of safety management, limitation of monitoring, and informational construction is very important in risk management. T e latest main harvests in the risk management field are presented, Research an risk management system and study on the distant monitoring system are two main aspects. Besides, Junctions of the distant monitoring system are expatiated here, which are working platform of management, analyzing platform of risk, monitoring platform of safety situation, commanding platforms of risk treatment, and black box of risk.
