Embodiment Construction
[0040] The plane of the prestressed tendon passing through the dome of a nuclear power project is as follows Figure 4 As shown, there are a total of 180 prestressed tendons 1, each arranged at an average of 2°, numbered 1-180. The prestressed tendons 1 passing through the dome are two orthogonal layers. There are 52 prestressed reinforcements 1.1 in the lower layer, 26 on each side passing through opposite directions, all along the directions of 60° and 240° (coordinate axis YY direction); the upper layer of prestressed reinforcements 1.2 There are 52 in total, 26 on each side passing through each other, all along the directions of 150° and 330° (coordinate axis XX direction), perpendicular to the prestressed tendons in the directions of 60° and 240°.
[0041] Establish an overall three-direction Cartesian coordinate system X, Y, and Z, where X is 90° and 270°; Y is 0° and 180°; Z is vertical to the XY plane, which conforms to the right-hand rule.
[0042] The local plane Ca...
