Comprehensive Fuzzy Evaluation of the Safety of Existing Buildings During Tunneling Construction in Urban Areas
(1 School of Civil and Architectural Engineering, Wuhan University, Wuhan, Hubei 430072; 2 Wuhan RSM Intelligence Geotechnique Co. Ltd., Wuhan, Hubei 430071; 3 State Key Laboratory of Geomechanics and Geotechnical Engineering, Institute of Rock and Soil Mechanics, Chinese Academy of Sciences, Wuhan 430071)
Abstract Generally, bored tunnels in urban areas are characterized by a shallow depth, a large section, poor surrounding rock, dense buildings above the tunnel, and high-risk construction. Aiming at the safety risk to existing buildings during tunneling construction, the three influential factors of building performance, tunnel condition, and in-situ monitoring data are considered and a two-level fuzzy comprehensive model is established to dynamically evaluate the safety of existing buildings and determine reasonable safeguarding measures for buildings according to evaluation consequences. Using the case of the Wushancun tunnel passing under existing buildings on Chenggong avenue in Xiamen, construction safety was evaluated and relevant measures were adopted according to evaluation consequences, and sound results were achieved.
