| description | The invention relates to a method and a device for evaluating ground surface delayed deformation by underground water level variation. The method comprises the following steps: acquiring deformation time sequence data in a preset range of the ground surface; constructing an objective function, and inputting the deformation time sequence data into the objective function; optimizing a PSO algorithm, combining the PSO algorithm with a Newton iteration algorithm to construct a hybrid algorithm, and resolving the objective function by using the PSO algorithm and the hybrid algorithm to obtain two groups of parameter resolving results; comparing the forward deformation time sequence of the parameter calculation result with deformation time sequence data, and calculating two first classification indexes; comparing the first classification indexes, and selecting a target parameter calculation result in combination with a lag coefficient k; and calculating a second classification index based on the target parameter ca |
