Design Analysis of Shuangji River Drainage Aqueduct Body with Large Flow

On the basis of summarizing the completed structural types of aqueduct both at home and abroad, combined with the structural design of Shuangji River drainage aqueduct in China South-to-north Water Transfer Project (SNETP), the aqueduct body structural form was selected. The analysis and discussion has been done with three typical structure forms of Shuangji River aqueduct, the two mechanical construction schemes by aqueduct-making machine and aqueduct-installing machine have been researched. The results show that the aqueduct with the character of large flow, big section, large loads and gentle gradient should be comprehensive analyzed on the mechanical behavior, construction scheme and construction cost to select the appropriate structural style for improving the quality and efficiency. The results provide valuable reference for designing the similar aqueduct.
