In order to solve the problem of “attaching importance to the construction while neglecting the evaluation” in construction of continuous rigid frame bridges in China, a post-construction evaluation system was established by taking the elasticity modulus of concrete, frictional loss of prestress and loss of prestress as the indexes, and a three-level fuzzy comprehensive post-design evaluation model was built. The continuous rigid frame bridge on the Chongqing-Hechuan segment of Lanzhou-Haikou Expressway was taken as an example to conduct a comprehensive post-design evaluation. The results showed that the studied bridge was evaluated and categorized into Category II in the bridge design evaluation system, indicating a good design and operation state of this bridge. Suggestions and countermeasures were proposed for the design of continuous rigid frame bridges, with a vision to provide a basis for construction of bridges of the same type.
