Study On Bridges' Reliability Evaluation

This thesis intruduces the concept & development of engineering reliability specially it relates bridges' reliability & many aspects of reliability evaluation.This thesis also intruduces the used methods on reliability evaluation of reinforced bridges,it intruduces some inspection methods & technology.Two-way arch bridges have big weight in existing bridges in our country,they have large quantity & locate all over the country.For some reasons,they behave aging & diseases.For the purses of assuring transportation safety,highway salibility,having the existing bridges to be used sufficiently & using the maintain money properly,it is necessary to do proper reliability evaluation for two-way arch bridges.Consultes on the base of large quantity of domestic & foreign literature,this thesis uses engineering survy & others' evaluation experience & advances factors analysis & system synthesis method for two-way arch bridge.This method overcomes the shortcomings & abuses that the used methods have.It has high veracity,strong adaptability & good maneuverability.Furthermore,it intruduces the experience of static load test for large-sized T-beam.
