摘要
Abstract
During service,bridge structures suffer from various types of damage due to the influence of multiple factors.Bridge inspection is the current verification method to determine whether bridges can continue to be used after reaching the design service life.Bridge inspection includes conventional(appearance)inspection and bearing capacity inspection.Its main tasks are to comprehensively detect the deterioration and damage of in-service bridges,carry out safety evaluation,determine the actual bearing capacity of structures,judge whether the damage threatens the bearing capacity and durability of bridges and affects subsequent use,and provide technical condition assessment and maintenance&reinforcement suggestions for bridges.关键词
