摘　　要：部分水利工程在使用过程中随着时间推移会出现不同程度的病害,从而严重影响其正常使用。八都水库输水渡槽投入运行至今已超过20 a,采用模糊评价法,通过现场安全检测以及安全复核计算分析,并邀请水利专家根据渡槽现场检测及结构验算结果对渡槽健康状态进行评分,取评价占比的最大值作为U型薄壳输水渡槽结构稳定性的最终评价结果。结果表明,渡槽槽身、支撑结构存在不同程度的老化、损坏、漏筋等病害,但仍处于相对完整的可运行状态,需减少流量运行或进行除险加固后才能继续正常运行。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 evaluate 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 leakage and other diseases,but they are still in a relatively complete and operable state,requiring reduced flow operation or reinforcement before normal operation.
