Analysis On The Risk Factors Of Low - Impact Development Technology Application And Countermeasures

Advancements in science and technology, and social developments have facilitated the high and new technology to be applied and promoted in daily life, and been playing an increasing significant role. Compared with other events, high-tech belongs to high-risk activities with more risk factors, which have caused serious effects on the promotion and application of high-tech.The Low Impact Development technology(LID), which has been treated as a new technology and methods to effectively solve the more and more common and serious problem of urban waterlogging in our country, has caused widespread attention outside the industry. LID was recently introduced in china and people have low awareness of it, in addition, most design personnel, construction personnel and maintenance personnel lack expertise in it. Like many other high technologies, the practical application of LID will face many risks. According to the theory of risk management, this paper aimed at the study of the application of LID and its risks. Following the general steps of risk management research and combining with the characteristics of the practical application of LID, we want to identify the possible risks in its application and put forward a reasonable counter-measure.With a variety of analysis methods, we have analyzed the priority of risk through the quantitative model and put forward a reasonable coping strategy based on the practical case study, hoping to provide a certain amount of experience in the risk management during the application of LID technology. The main content of the paper is as follows:(1)Summarize the application and research status of LID technology, and the importance of risk research to the technology.(2)Introduce the relative theory of risk and risk management for the preparation of next step.(3)Through the methods which include actual project site investigation, expert interview, brainstorming, Delphi and so on to identify and evaluate the risks that exist in the application of LID technology. Ten relatively important risks have been selected and then prioritize them using analytic hierarchy process.(4)Finally, put forward opinions on the disposal counter-measure before and after the event of each risk according to the priority level of risk, emphasize the necessity of risk monitoring, point risk management as a continuous process, ensure the change of risks to continuously supervise and control them during risk risk monitoring.
