Study on Condition Assessment of Highway Bridge, Normal-Speed and High-Speed Railway Bridge

There are lots of theories and methods about condition assessment for highway bridge, and gradual perfection for normal-speed railway bridge, but only little for high-speed railway bridge, especially large-span and special structures. After studying on the contents, methods, theories and evaluation indexes of highway bridge and normal-speed railway bridge, combined with the characteristics of high-speed railway bridge, index system for high-speed railway bridge(medium and small span, large-span or special bridge structures) was conceived and discussed, which laid the foundation for the development of condition assessment of high-speed railway bridge.
