Research on Design and Construction Technology for Large Flow Prestressed Concrete Aqueduct

With the application of latest engineering science as well as effective theory, technology, material and method in other fields of civil engineering to the study on design and construction technology for large-scale aqueducts, while combining the typical project to develop the theory analysis, model experiment and site experiment study,some scientific, economic and reasonable methods in design and construction have been given in the paper. Applying those systems to optimal design and construction of large flow prestressed concrete aqueducts, we can save 10%-20% of the investment, the economic span of single span of aqueduct reaching 30-50m, and the effect of vibration absorption above to 30%. Sothe cracking problem of the flume can been solved basically, and aqueduct engineering will operate safely.
