Cao River aqueduct is the large-scale aqueduct that has been designed and constructed for the first time in China, for the great technical difficulties in structure form, there's no engineering experience or theoretical method for reference in domestic and abroad. Therefore, for mastering the stress characteristics and deformation law of aqueduct structure more overall and deeply, the impounding test of trial span was carried out before formal operation. Deformation characteristics of the aqueduct under impounding condition were analyzed in detail. The maximum deflection at mid-span of longitudinal beam was 0.98mm when three aqueducts all impound to 5.4m, the change range is small and in the allowable range of design and specification , which means the structure of aqueduct was reasonably designed and also provided important reference for the later operation and management.
