By means of the optimization features of the shuffled frog leaping algorithm, the solution to the statistical model for dam safety monitoring was converted to the optimization of the multi-objective function. The adjustment coefficients were introduced to correct the change of the regression factors. Considering the relationship between the adjustment coefficients and the regression factors, the values of the adjustment coefficients and the regression factors were synchronously determined by use of the shuffled frog leaping algorithm. A weighted deformation forecast model for a concrete dam was established based on the shuffled frog leaping algorithm. The engineering examples show that the proposed model has superior long-term forecasting ability, and it may enhance the forecasting accuracy of the traditional statistical model for dam safety monitoring. It has certain application value for engineering in the field of dam safety monitoring.
