Study On The Metro Engineering Risk Management Under Complex And High Crisis Condition In Shanghai

At present, risk management of engineering project construction was taken more and more seriously in domestic and foreign. Especially in big-scale work project, the risk factors, in its construction and operation process, must be carried on the analysis and determined its dangerous ranks, then to proposes the practical and feasible project countermeasure and the processing measure. Project risk management has provided the safe production operation environment for the project.The Shanghai subway9-2engineering project’s influencing factor includes short time, high important rank、strict quality control、high security environmental protection demand, heavy high engineering construction duty、high construction management specification, and so on. This article,in view of these influencing factors, carries on the risk management technology of the Shanghai subway9-2engineering projects to conduct the research, in which, many ways and methods were integrated used, such as the investigation and study, the theoretical analysis, the Scene checkup, and many technology and the methods of the subway engineering construction were involved, fully unifying the project’s actual situation, in order to avoiding, melting, transferring risk and sharing or reducing the risk loss, providing the powerful safeguard for safe, fast, high quality of the engineering project and providing reliably models and experiences for the similar engineering construction.Based on risk management theoretical analysis, Shanghai subway9-2project risks mainly includes highly, moderate and general three rank risks, altogether34items (time) material risk source, forgiving majority of risk factor and risk source in this kind of engineering project construction, in order to laying the solid foundation for following mechanical control measure research. After analysising engineering geology condition, peripheral environment as well as itself structure and so on, optimized construction parameter could guarantee personnel, equipment and building structure safety in project construction process in the enormous degree. Proposed in this article, the construction control countermeasures, the technical measures, the construction requests as well as the safety controls which is related, can monitor the major part risk source well, and may ensure the project construction security, the quality and the progress. What may be obtained after this article is that, only unifying fully scene engineering geology condition, peripheral environment as well as project itself structure to analysis, can carry on the management effectively to the risks.
