The invention provides a determination method for an indoor rapid freeze-thaw cycle and natural freeze-thaw cycle relation of concrete. The method comprises the following steps: step 1: obtaining a design matching ratio and a strength grade of hydraulic concrete of a concrete water conservancy; step 2: deigning and expanding N types of freeze-thaw tests of different freeze-thaw cycles at the lowest temperature, wherein N is greater than or equal to 3, so as to obtain concrete degradation testing data under different freeze-thaw times; step 3: establishing a concrete freeze-thaw injury model ofa freeze-thaw cycle temperature procedure; step 4: establishing a relation between an indoor rapid freeze-thaw cycle and a natural freeze-thaw cycle of the concrete. According to the determination method for the indoor rapid freeze-thaw cycle and natural freeze-thaw cycle relation of the concrete, provided by the invention, the problem of an existing method that influences, caused by the freeze-thaw cycle temperature procedure, on concrete freeze-thaw injuries can be solved, and natural freeze-thaw degradation of an on-site water conservancy can be quantitatively guided by indoor rapid freezing and thawing.
