在设计输水渡槽时,保证建筑物的安全性是至关重要的。实践证明,如果将槽身设计成三向预应力,不仅可以提高结构的抗裂性,减小构件变形,还可节省工程量和投资。 In the design of aqueduct, to ensure the safety of the building is essential. Practice has proved that if the body is designed to three-way prestressed, not only can improve the structural crack resistance, reduce component deformation, but also to save the amount of engineering and investment.
