[0035] Specific implementation plan
[0036] The implementation of the technical solution will be further described in detail below in conjunction with the drawings.
[0037] 1. The concept of generalized water pipe nodes:
[0038] Such as figure 1 As shown, the water pipes in the concrete generally use serpentine pipe loops, the vertical spacing of the water pipes is generally equal to the thickness of the pouring layer, and the horizontal spacing is generally 1.5m~3.0m. When calculating with finite element, the calculation area must be meshed first, that is, the calculation model is established. The diameter of the cooling water pipe in large-volume concrete is about 32mm. Compared with the influence area of the water pipe, its volume is negligible and can be regarded as a line in the concrete, which will not greatly affect the accuracy of the calculation result. The nodes in the concrete through which the cooling water pipes pass are defined as generalized water pipe nodes. T...
