This paper analyzes reasons of diseases of some suspension bridge in Tibet Autonomous Region to expatiates assessment of its carrying capacity.The paper adopts inspection of diseases at earlier stage and quasi -static test of generalized influence curve of structures to correct the model of finite element theory to make clear the actual carrying capacity of structures.The whole analysis and assessment process mainly includes four parts:1)Inspection of diseases at early stage;2)Analysis for reasons of diseases;3)confirmatory load test of bridges;and 4)Assessment of carrying capacity of bridges.
