摘要：Lianghu pump station of a large-scale water conservancy project under construction is characterized by complex structure, large scale and large size of solid body pouring block, while the previous discrete model of cooling water pipe is difficult to be successfully arranged in the concrete grid and requires a large amount of computation. In this paper, the improved embedded model of cooling water pipe, which considers the change of the water temperature in the cooling water pipe, is adopted to simulate the temperature control of the large pump station during the construction period. The results show that, with the help of the measured data, although the error rate of the improved embedded model of cooling water pipe at the highest temperature is 5% higher than that of the discrete model, the calculation efficiency is increased by about 40% in comparison with the discrete model. The comprehensive profit is improved by nearly 35%. It is worth popularizing and applying in the simulation calculation of temperature field of large pump station structure during construction period. Finally, the results of the two pipe models are compared and the relevant suggestions are given.
