The present application relates to the field of
landslide soil strength prediction, and more particularly to a
landslide soil strength prediction method based on CT scanning
microstructure parameters. The content includes: CT scanning of
landslide soil samples, obtaining CT images of landslide soil, and performing gray scale normalization
processing; after gray scale normalization
processing, a direction-scale joint structure response operator is introduced to construct a structure
density field; a
continuous scale disturbance calculation mechanism is introduced, the CT image of the landslide soil is divided into multi-scale
voxel blocks according to the spatial scale, and based on the structure
density field, the normalized structure disturbance strength index under each spatial scale is generated; based on the normalized structure disturbance strength index under each spatial scale, the scale response parameter is generated; a structure response prediction model is introduced, and based on the structure
density field and the scale response parameter, the
shear strength of the landslide soil is predicted. The problems of the existing landslide
soil strength prediction method, such as lack of structure resolution capability, low prediction accuracy and difficulty in adapting to multi-
scale structure characteristics, are solved.
