This invention provides a method for analyzing the spatiotemporal stability of landslides considering the microscopic characteristics of in-situ creep of the slip zone. The method involves identifying the landslide geological conditions, conducting in-situ direct shear creep tests, microscopic scanning tests, and numerical tests to reveal the influence of microstructural changes on the in-situ shear creep mechanical properties. It defines and quantifies microstructural factors, constructs an evolution model of the slip zone's microstructure and mechanical properties, and then establishes a constitutive model of in-situ shear creep of the slip zone incorporating microstructural factors. Based on landslide monitoring data, the time history of the landslide displacement field is obtained. A dynamic spatial weight matrix is ​​introduced and corrected using slip zone and slip body constitutive models to establish a spatiotemporal evolution model of the landslide with the dynamic spatial weight matrix as its core. A displacement field prediction platform based on a displacement field database and the spatiotemporal evolution model is built to predict the displacement field, thereby enabling real-time searching of the slip surface. Combined with mechanical calculations, this achieves stability analysis of the landslide at both spatiotemporal scales.
