| Abstract: | According to the characteristics of effect that the demolition of bridge to its nearby bridge, based on the exisiting research results, the way how the demolition have effect on its nearby bridge is analysed. From the angle of security risk assessment, the common risk index assess model about removing construction to nearby bridge is established in reference to the basic principles and steps of Risk index safety evaluation method. Based on expert evaluation, qualitative analysis of the security risk caused by removing construction is done. |
