盾构法隧道施工是工程建设中的高风险业务,众多风险不确定因素交错复杂。相应研究目前主要偏重于技术风险及其理论研究,分析方法以定性指标定量化的手段,其有效性在实践应用中受到一定制约;同时,相关研究对经济、技术、环境的系统分析相对不足。基于盾构法隧道施工的特点,系统探讨了风险因素的结构体系和全过程的风险管理流程,并引入知识管理的理念和方法,建立了较全面的盾构法隧道施工风险因素和风险管理相关数据的采集、组织、处理和应用的方法,形成了知识积累机制和知识管理信息平台,提升了风险管理研究的实用价值。 Shield construction Tunnel construction is a high-risk business in construction, with many uncertainties in risk being complicated. At present, the corresponding researches mainly focus on technical risk and its theoretical research. The method of analysis is quantitatively determined by qualitative indicators. Its effectiveness is constrained in practical application. At the same time, systematic researches on economy, technology and environment are comparatively inadequate. Based on the characteristics of shield tunneling, the system of risk factors and the risk management process of the whole process were systematically discussed. The concept and method of knowledge management were introduced to establish a more comprehensive shield tunneling risk factors and risk management Data collection, organization, processing and application methods, the formation of knowledge accumulation mechanism and knowledge management information platform, enhance the practical value of risk management research.
