Due to the increase of the size of the gate hole and the thickening of the concrete floor and pier， the mutual restriction between the floor and pier is strengthened and the deformation coordination between them is reduced. It is easy to be affected by the external environment temperature， and it is easy to produce excessive tensile stress during the construction period and operation， and the situation of temperature control and crack prevention is severe. The primary task of temperature control and crack prevention of sluice gate is to determine the temperature control standard. However， the existing sluice gate design code only makes some principle provisions for the temperature control of sluice gate concrete， but does not give a detailed description of how to determine the temperature control standard. That is， the temperature stress control standard of sluice concrete is proposed first， then the permissible temperature difference of foundation and upper and lower layers is determined， and the maximum permissible temperature during construction is determined according to the quasi-stable temperature field of sluice structure. The temperature stress control standard of concrete of sluice structure can be determined by safety factor method， and it is recommended that the value of safety factor against cracking should not be less than 1.30. The value of stress constraint coefficient is calculated by the fitting formula given in this paper. Finally， taking a large orifice sluice in the Ganjiang River as an engineering case study， the corresponding temperature control standards are proposed. The research results can provide reference for the formulation of temperature control standards for a large orifice sluice.
