发布时间：2018-08-17 16:14
【摘要】：基于不同风险因素对高速铁路的安全评价影响程度不同,而实际工程项目往往按照工程经验来实施,具有一定的不确定性与不可靠性,因此,需要对安全评价的各个因素关联度进行分析与研究。以灰色关联分析理论为基础,建立2种关联度模型,计算各个风险因素对安全评价项目的关联度的贡献值,确定不同安全评价中的最主要的影响因素。研究结果表明:加固范围对于盾构下穿高速铁路的安全评价起重要的作用。结合分析所得的结果,利用FLAC3D软件计算不同加固范围下的安全评价值,确定最合理的加固范围。通过工程应用,表明灰色关联分析在盾构下穿高铁工程中具有一定的理论应用,为类似的工程提供一定的理论与实践参考。
[Abstract]:Based on the different risk factors, the degree of influence on the safety evaluation of high-speed railway is different, but the actual project is often carried out according to the engineering experience, which has certain uncertainty and unreliability, so, It is necessary to analyze and study the correlation degree of each factor of safety evaluation. Based on the theory of grey correlation analysis, two kinds of relational degree models are established to calculate the contribution of each risk factor to the related degree of safety evaluation project, and to determine the most important influencing factors in different safety evaluation. The results show that the reinforcement range plays an important role in the safety evaluation of high-speed railway under shield. Combined with the results of the analysis, the most reasonable reinforcement range is determined by using FLAC3D software to calculate the safety evaluation value of different reinforcement range. Through the engineering application, it is shown that the grey correlation analysis has certain theoretical application in the shield tunneling project, and provides a certain theoretical and practical reference for similar projects.
