Soil body surface crack development pre-judgment method

The invention discloses a soil surface crack development pre-judgment method, and belongs to the field of infrared remote sensing-geological engineering. The method comprises the following steps: S1, shooting the surface of a to-be-monitored soil body by adopting an infrared thermal imaging camera to obtain a soil body surface temperature field; s2, drawing a soil isotherm diagram according to the soil surface temperature field; and S3, determining a main fracture development area on the surface of the soil body according to the soil body isotherm diagram. According to the method, the change of the surface temperature field in the cracking process of the soil body is analyzed through the soil surface temperature field information obtained in real time, then the crack development on the surface of the soil body is pre-judged, the crack development on the surface of the soil body can be effectively and rapidly monitored, and the method is a simple and efficient soil body crack development pre-judgment method. 本
