本文基于专家调查法对大跨度钢桁梁桥建设期安全风险评估开展研究。首先采用专家调查法进行大跨度钢桁梁桥的运营风险因素识别和指标体系划分,再针对指标体系开展综合评判分析,进行大跨度钢桁梁桥的运营期风险定量评估,分析结果为工程运营期的风险控制提供依据。研究结果表明基于专家调查法的工程运营期安全风险评估方法具有较好的实用性和合理性,可为相关工程运营期安全风险评估工作提供参考和借鉴。
Based on the expert investigation method, this paper studies the safety risk assessment of long-span steel truss girder bridge construction period. Firstly, the expert survey method is used to identify the operational risk factors and the index system of the long-span steel truss girder bridge. Then, the comprehensive risk assessment of the long-span steel truss girder bridge is conducted based on the comprehensive evaluation of the index system. The analysis results are as follows: Provide a basis for risk control. The results show that the method of risk assessment based on expert investigation has good practicality and rationality and can provide references for the safety risk assessment in the relevant project operation period.
