| Abstract: | Based on practical engineering examples, the values of parameters of Gompertz curve by three-segment estimation method are achieved, and the Gompertz growth curve model is established to analyze the settlement data. Compared with the two groups of data, Gompertz growth curve model has good adaptability and precision in trend forecast. |
