【摘要】 只就技术风险角度试对台海隧道工程的各类技术风险识别、风险分析与控制以及风险管理等方面的问题进行初步探讨。介绍近年来国内外对长大隧道和重大工程建设项目所已进行的风险分析情况;对采用隧道掘进机(TBM)开挖施工的技术性风险进行分析;分析并提出隧道施工期和运营期的工程安全性研究与评价所应考虑的主要问题;同时对工程风险管理提出了实行社会化的工程保险机制和保险体系及量化、科学化分析评价的要求。经风险识别得出的几种主要技术风险进行分析将有利于估计工程建造费用并掌控工期,进而讨论其诸多不确定性与风险程度,为确定这些重要指标的可信度提供科学依据。更多还原

【Abstract】 The author tries to make a preliminary study on the technology risk identification,risk analysis and risk control as well as risk management of Taiwan Strait Tunnel from the aspect of technology risk.First,the author presents some risk analysis information on long tunnels and major projects both at home and abroad in recent years,and analyses the technology risks of TBM-constructed tunnels.Then,he analyses and puts forward some issues that need to be considered in project safety study and safety evaluation during tunnel construction and operation.At the same time,the author brings forward the requirements for the application of socialized project insurance system and scientific risk analysis and risk evaluation method in project risk management.The analysis on the several main technology risks gained from risk identification is helpful to the cost estimation and construction schedule control.What is more,the study on the several uncertainties and risk degrees can provide scientific basis for the determination of these main indexes.更多还原
