铁路工程勘察设计项目全寿命周期风险管理研究

摘要

研究目的:铁路工程勘察设计项目管理具有较强的动态性特征,项目实施过程中面临的风险常因环境的影响而发生变化.为降低风险造成的损失,基于铁路工程勘察设计工作的全寿命周期角度,应对项目中可能出现的风险进行全面管理.本文通过科学构建风险管理模型,以实现有效进行风险识别、风险分析以及风险控制的目的,确保项目目标的顺利实现.研究结论:(1)应从项目全寿命周期角度,将风险管理体系集成平台、风险因素分布与风险管理流程有机结合;(2)铁路工程勘察设计过程中的风险分布具有显著的波动性;(3)基于PDCA环构建循环闭合的铁路工程勘察设计项目风险管理环,可以提高风险管理流程之间协同工作的效率;(4)本研究成果对从事铁路工程勘察设计及相关工作的单位具有一定借鉴意义.%Research purposes:The railway construction survey and design project management has strong dynamic characteristics.The risks in the process of project implementation are often influenced by environmental impact.The comprehensive risk management process should be implemented based on whole-life cycle perspective to reduce the losses caused by risks.The job of risk identification,risk measure and risk control can be taken effectively through rational designed risk management model.The project objectives can be successfully achieved through the above measures.Research conclusions:(1) The whole-life cycle risk management should organize risk management integration system platform,risk factor distribution and risk management process;(2)The risk distribution in the process of railway construction survey and design have significant volatility characteristic;(3) The construction of closed project risk managementloop can improve the efficiency of collaborative work between risk management processes;(4)The conclusions of this paper have reference value for railway construction survey and design institutions.
