Description
Technical Field
The invention relates to the field of data processing methods, in particular to a method for analyzing the annual load change process of a waterproof curtain wall.
Background
The high dam reservoir is easy to form the water temperature layering phenomenon of the reservoir in spring and summer, the water body with higher water temperature is positioned at the upper layer, and the water body with lower temperature is positioned at the lower layer. The water intake of the power station has multiple elevations and is low, and the water temperature is low-temperature water, so that the problem of discharging the low-temperature water in spring and summer is caused. The discharge of low-temperature water in spring and summer of the power station will affect the fish reproduction and crop growth of downstream riverways, and cause serious ecological impact.
The water-resisting curtain wall is one of engineering measures for raising the temperature of the discharged water of the power station, and the principle is that a water-resisting curtain wall positioned under water is built at the upstream of a water intake to block low-temperature water at the bottom layer, so that water with higher temperature at the upper layer passes through the top end of the curtain wall and enters a water inlet of the power station, and the purpose of raising the temperature of the discharged water of the power station is achieved.
When the water-resisting curtain wall is in operation, because the water temperature at the upstream side of the curtain wall is low and the density is large, and the water temperature at the downstream side is high and the density is small, the load of the water-resisting curtain wall is influenced by the water temperature structure of the reservoir. Meanwhile, the better the water-proof curtain wall is discharged, the higher the water temperature at the downstream side is, the larger the temperature difference between the upper side and the downstream side of the curtain wall is, and the larger the load is. In the current industry, the stoplog door can be used for improving the temperature of the discharged water, but the stoplog door is built at the water inlet of the power station, so that the requirement of analyzing the annual load change process is avoided. The trash rack similar to a waterproof curtain wall structural system has mature design specifications, but the technology only needs to calculate the load in the most dangerous running state, and has no requirement for analyzing the annual load change process. The water-proof curtain wall belongs to a novel reservoir water discharge temperature improvement measure, and during design, the annual change process of curtain wall load needs to be analyzed, and proper water-proof curtain wall design parameters and an operation scheduling scheme are searched, so that the balance of the load and the water discharge temperature improvement effect is achieved. At present, no mature load calculation method can carry out annual-scale load change process analysis in the industry, and the existing load calculation methods cannot be directly used for calculating the load of the waterproof curtain wall because the influence of a water temperature structure on the load of the waterproof curtain wall is not considered. In conclusion, the deficiency of the mature calculation method for the load of the waterproof curtain wall seriously restricts the design level of the industry on the waterproof curtain wall and limits the research depth of the waterproof curtain wall, so that an analysis method capable of calculating the annual change process of the load of the waterproof curtain wall is urgently needed.
