Due to the influence of various random factors during the construction period and operation period, the temperature field of gravity dam becomes random.This paper comprehensively considers the environmental temperature (including temperature and reservoir water temperature), the concrete adiabatic temperature rise, warehousing temperature, concrete and bedrock Based on the stochastic finite element method, the calculation method of random temperature field of gravity dam is given. The construction process of a typical gravity dam is modeled by a given construction schedule, and the construction period and pre-operation period The random temperature field is calculated, and some useful conclusions are drawn.
