Abstract
In the calculation of thermal stress of arch dams, the reservoir water temperature is an important boundary condition, and high calculation accuracy is required, especially for the upstream water temperature of high arch dams.There are many influential factors for reservoir water temperature, such as the channel type, the reservoir inflow, the inflow temperature, weather conditions, etc.and how to consider the impact of various factors on the distribution of water temperature is significant for calculation accuracy.In this paper,a two-dimensional lateral averaged hydrodynamic model was used to simulate the dynamic temporal and spatial distribution of water temperature in large reservoirs that have similar hydrodynamic characteristics on Jinsha River, such as Xiangjiaba, Xiluodu, Baihetan and Wudongde.Taking Xiluodu Reservoir as the case, sensitivity analyses of the inflow, the inflow temperature and weather conditions were carried out, which can provide important reference for the reservoir temperature calculation in the following projects.关键词
