The cave information includes cave shape information and cave location information.

[0045] In step 102, a Kriging proxy model is established based on historical cave information.

[0046] In a specific embodiment, the Kriging proxy model is composed of a global regression model and a nonparametric Gaussian random process based on local errors. In essence, the historical cave information near the cave information to be processed is linearly weighted combined to estimate the cave information to be processed.

If it converges, the optimization is stopped. If not, the next round of optimization is performed based on the Sigmoid mapping function after this round of optimization until the objective function of the Sigmoid mapping function converges and the optimization is stopped to obtain the optimal bias parameter.

[0059] In step 108, the roadbed treatment information is output according to the updated empirical parameters.

[0060] In a specific embodiment, the roadbed treatment information includes the diameter, depth, and spacing of the piles; the spacing of the tamping points; the water content and density of the grouting, and the like.

[0061] In a specific embodiment, the relationship between the updated empirical parameter and the Sigmoid mapping function is as follows:
