Structural Stability Analysis of U-shaped Thin Shell Aqueduct:Case Study of Badu Reservoir
In some water conservancy projects,various degrees of diseases have emerged in the course of use,which seriously affects its normal use.It has been more than 20 years since the aqueduct of Badu Reservoir was put into operation.Fuzzy evaluation method was adopted to evaluate the health status of aqueduct through on-site safety testing and safety review calculation and analysis,on which water conservancy experts were invited to eval-uate according to the results of on-site testing and structural verification of aqueduct.The maximum evaluation ratio is taken as the final evaluation result of the structural stability of U-shaped thin shell aqueduct.The results show that the aqueduct body and supporting structure have varying degrees of aging,damage,reinforcement leak-age and other diseases,but they are still in a relatively complete and operable state,requiring reduced flow opera-tion or reinforcement before normal operation.
