A method for constructing a digital twin monitoring model for slopes based on a proxy model includes S-S. S, a slope geometric model consisting of M triangular facets is constructed. S, a first training dataset is constructed for pretraining a pre-proxy model by using the slope geometric model. S, monitoring data of the M triangular facets are collected in real-time to construct a second training dataset for training the proxy model. S, a warning cloud map of the slopes is generated. The method uses the slope geometric model to obtain simulation data under multiple physical field conditions. It constructs training dataset of pretraining pre-proxy model based on the simulation data, which greatly reduces training samples. Moreover, the multiple base learners in the proxy model can reduce the computational bias of a single time-series analysis model, improving the prediction accuracy of the proxy model.
