We established how to observe and describe high-quality undisturbed drilled cores using methods and knowledge of structural geology, and consequently obtained criteria to differentiate nontectonic faults and tectonic faults. We clarified the relationship between the development of foliation and gravitational rock deformation and the development processes from gravitational slope deformation to first-time landslide.We simulated the subsurface gravitational slope deformation that have been obtained by high-quality drilled cores by using finite difference methods, demonstrating that the internal stress strain conditions in the slope change according to the river incision forming the shear zones, which have been identified in the nature.

建立了利用构造地质学的方法和知识观察和描述高质量原状岩心的方法，从而获得了区分非构造断层和构造断层的标准。阐明了叶理发育与重力岩体变形的关系以及重力边坡变形到首次滑坡的发展过程，利用有限差分法模拟了高质量钻孔岩心获得的地下重力边坡变形，论证了边坡内部应力应变条件随河流下切形成剪切带而变化，这些已经在自然界中被识别出来。
