| Abstract: |
Based on the analysis about the hydrogeological conditions and engineering geological conditions, the paper has made the analysis on the possible risks of the deep overlying stratum foundation and established the risk evaluation index system during the foundation operating period. Such methods as AHP, Delphi method and fuzzy comprehensive evaluation method, etc. are adopted to make the quantitative analysis on the risk factors and establish the risk judgment model. According to the actual engineering of Taizhou Bridge, the paper has evaluated the risk of the foundation during the operating period at the condition of deep overlying stratum. The evaluation results can confirm the design of the bridge site is reasonable, and provide the reference for the risk management of the bridge foundation during the operating period. |
