Overall Risk Assessment of Construction Safety of Extra-large Highway Bridges
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.
