Taking the properties of aqueduct in the middle line of the South-North Water Diversion Project, such as high flow, long span, large load and cross section and so on, two schemes about layout of prestressed steel strands are put forward. In order to guarantee safety of the project and structural optimization, 3-D FEM is adopted to study the regularity of distribution of stress and strain on control section under each condition of the two schemes. The results show that the design of steel strands in the first scheme (wavy steel strands) is much more reasonable and meets the requirements for anti-crack and deflection of the aqueduct body.

Taking Shahe and Dalang River aqueducts as an example, this paper introduces a movable and reusable waterproof device for aqueduct construction, which is suitable for construction scheme of structure repair and waterstop belt replacement for large-scale water delivery aqueduct of Shahe River and Dalang River in South-to-North Water Diversion Project. It aims to solve structural damage and waterstop belt leakage of the aqueducts of Shahe River and Dalang River in the South-to-North Water Diversion Project, realizing the aqueduct construction with uninterrupted water supply, and structure repair and waterstop belt replacement in the waterless environment separated by watertight device in the aqueduct construction.
