摘　　要：大吨位T形刚构转体桥施工作业技术难度大,不确定因素多,对其施工过程展开风险评估研究非常必要。根据风险评估与管理理论,利用综合识别法识别出转体过程中的施工风险因素,并对转体过程的主要风险源进行风险评估,提出相应施工风险控制对策,为今后类似桥梁施工管理及风险评估提供借鉴。Due to the technical difficulty and uncertainty of rotation construction of large tonnage T-shaped rigid frame bridge,it is necessary to perform construction risk assessment.Based on the risk assessment and management theory,the risk factors in the construction process are identified accord-ing to the comprehensive identification method.The main risk source of the construction process is as-sessed and the corresponding risk control measures are proposed.It is a good reference for the con-struction management and risk assessment of similar bridges.
