The Analysis and Estimation on Risk Factors in Engineering Project Life-Cycle

In recent years the engineering accidents, especially those occurred to large-scale public projects were paid more and more attention by engineers and even the normal public. The large-scale public projects involved such numbers of participants and complicated procedures, which challenge to the traditional project security management. There is should be anew method to do with the modern engineering's risk manage requirement. This article summarized the risk factors in all the engineering process as the risk theoretical research foundation. In this paper, considering the disadvantages of disseverment and isolation each engineering process stages of traditional engineering risk management method, the idea of project's life-cycle method is introduced in the risk analysis for improvement the traditional disadvantage. This article also shows how to determine the risk sources and the risk liability by analyzed the stages' risk possibility of project life-cycle. These works will help to build up an analysis basement for engineering risk control research.
