摘要
依托成都地铁13号线娇子立交盾构隧道穿越立交桥桩基群施工项目,首先对盾构隧道施工过程中的典型高风险事件进行了识别分析,随后基于模糊数学理论和层次分析法,对该盾构隧道全过程穿越施工开展了风险分析,明确了施工过程中各风险事件的风险等级。该研究可作为盾构隧道穿越桩基群施工的预防措施和评估提供参考依据。
Based on the construction project of Jiaozi overpass shield tunnel crossing overpass pile foundation group of Chengdu Metro Line 13,this paper first identified and analyzed typical high-risk events in the process of shield tunnel construction,then carried out risk analysis on the whole process of shield tunnel crossing construction based on fuzzy mathematics theory and analytic hierarchy process,and determined the risk level of each risk event in the construction process.This study can be used as a reference for the preventive measures and evaluation of shield tunneling through pile groups.
