Concrete interface pre-peak shear curve simulation method based on Hordan distribution

The invention discloses a concrete interface pre-peak shear curve simulation method based on Hordan distribution. The method comprises the following steps: acquiring a distribution function of Hordan distribution; applying the distribution function to the peak front section of the concrete interface shear curve to obtain a pre-peak shear curve initial simulation function; substituting the peak point coordinate of the pre-peak shear curve to obtain a parameter value of an initial simulation function of the pre-peak shear curve; correcting by adopting an exponential function to obtain a final pre-peak shear curve simulation function; and performing actual pre-peak shear curve simulation by adopting the pre-peak shear curve simulation function. According to the concrete interface pre-peak shear curve simulation method based on the Hordan distribution, the simulation model based on the Hordan distribution and the index correction coefficient is established, the established model can represent shear deformation of
