摘要
特大公路桥梁具有建设规模大,施工工艺复杂等特点.为了保证桥梁施工阶段的的安全,基于桥梁的建设规模、地质条件、气候环境条件、地形地貌条件、桥位特征、施工工艺的成熟度等评价指标,对桂林洛清江特大桥梁进行施工安全总体评估,明确重大风险源.最后,提出主要的控制措施,结合专家调查法,初步评估了该措施可将工程事故标准控制为1 级.
Abstract
The extra-large highway bridge has the characteristics of large construction scale and complex construction technology.In order to ensure the safety of the bridge construction stage,based on the evaluation indicators such as the construction scale,geological conditions,climatic and environmental conditions,topography and geomorphological conditions,bridge location characteristics,and ma-turity of construction technology,the overall construction safety assessment of the Luoqingjiang bridge in Guilin was carried out,and the major risk sources were clarified.Finally,the main control measures are proposed,combined with the expert investigation method,and the preliminary evaluation of the measures can control the engineering accident standard to level 1.
