A Study To Risk Management Model Of Highway Project

the paper systematically did reseach into highway project risk management model, on the basis of regarding a variety of risk in highway project as a kind of multi-level system,we firstly investigated the model in such aspects as risk origin, organization form of risk management, risk management processes, at the same time, we builded up a Frame-diagram of highway project risk management, according to the line shown in the Frame-diagram, the paper made a study of risk management integral layout for highway project, and proposed a idea to make use of comprehensive method to make risk management integral layout, under the guidance of risk management integral layout for highway project, we identified and classified a variery of risk existing in highway project, if we treated all risks in highway project as the same, no doubt ,the idea will increase burden of highway project,how to manage these risks differently ? at first,we made a estimation of possibile probability and influence risks occurring, based on which we evaluated these risks existing in highway project,including ascertaining risk grade , sequencing risks , analysing risks consequence and so forth, considering owner risk-endurence , the paper proposed three kind of method to ascertain risk-grade, we made use of Level-analysis method to sort risks in highway project, in the section, the paper proposed a kind of new expression-Risk Actangular Diagram(RAD) for risk sequence,and designed Risk Evaluation System(RES). in the risk consequence analysis, we made a study of several kind of relationship among risks to improve on highway project risk management and to reduce cost of risk management, through the evaluation of highway project risks, we can well understand which need to monitor and to control,which need to manage generally, by which the goal to manage risks differently is attained, from risk evaluation result, we need to make proper measures,which consist of Avoidance, Mitigation, Transference, Acceptance, to respond highway project risks, especially serious risks in highway project, the paper made a analysis of response measures to usual risks, risk monitoring and controlling means supervising plan performing case and staff performing plan case, in the section, the paper proposed a way to use RAD to track risks, and apply earned-value method into risk management for highway project to controll schedule and cost of highway project, at last, connected with practice of lin-chang highway project, we made use of the model to manage risks inhighway project tentatively.Through the reseach into highway project risk managenent model to provide a kind of method, clue for risk management of highway project, in short, the model, which need to make perfect endlessly in the highway project practice,will become really effective tool to manage risks in the highway project.
