盾构隧道下穿高速铁路的安全因素分析及应用
The analysis and application of safety factors of shield-underneath high-speed railway
摘要
Abstract
Although different risk factors have different influences in the safety assessment for High-speed railway. There is some uncertainty and unreliability when the real projects are often implemented by engineering experience in the past; therefore, it is necessary to analyze and investigate the correlation degree of each factor of the safety evaluation. Based on the Grey Correlation Analysis Theory, the Deng's Relational Model and Relative Relation Grade Model were set up to calculate each risk factors' condition to the Safety Evaluation Project and to determine the most important factors in different safety assessment projects. The results show that the reinforcement scope is the maximum correlation with the value of the safety assessment. Combined with the results of calculation and analysis, the model was applied in a certain engineering example, using the software FLAC3D to set up three-dimensional numerical model, conducting analog computation for shield excavation, and calculating the safety evaluation value in different reinforcement scopes. Through the application of engineering practice, it is indicated that Gray Correlation Analysis has certain theory application in the shield-underneath high-speed railway engineering, which can provide a reference for similar engineering projects.关键词
