基于模糊综合评判法的预应力混凝土连续梁桥悬臂浇筑施工风险评估

Cantilever Irrigating Construction Risk Assessment of Prestressed Concrete Continuous Beam Bridge Based on Fuzzy Comprehensive Evaluation Method

本文基于模糊综合评判法对预应力混凝土连续梁桥悬臂浇筑施工风险评估开展了研究。首先采用专家调查法和层次分析法进行预应力混凝土连续梁桥悬臂浇筑施工风险因素识别和指标体系划分,再针对两级指标体系开展模糊综合评判分析,进行悬臂浇筑施工风险定量评估,分析结果为工程施工风险控制提供了依据。研究表明基于模糊综合评判法的工程施工风险评估方法具有较好的实用性和合理性,可为相关工程施工风险评估工作提供参考和借鉴。

Cantilever irrigating construction risk assessment of prestressed concrete continuous beam bridge is studied in the paper based on fuzzy comprehensive evaluation method. First, using the ex- pert investigation method and the analytic hierarchy process to identify the risk factors and divide the in- dex system of cantilever irrigating construction. Then, the fuzzy comprehensive evaluation analysis is car- ried out for the two index system, and the quantitative evaluation of cantilever irrigating construction is conducted. The analysis results provide the basis for the construction risk control. The research shows that the engineering construction risk assessment method based on fuzzy comprehensive evaluation method is practicable and rational. And the researeh can provide reference for the construction risk assessment work.
