以往人们曾对滑坡的现象、成因、因素和发育规律等进行过大量的描述、观测和研究,并从斜坡稳定性方面研究滑带土强度的变化和稳定性计算方法。随着现代科学技术的发展,研究滑坡也涉及到更广阔的领域,引用了一些新的方法。如对滑坡作用理论的研究,已由宏 In the past, people have carried out a large number of description, observation and research on the phenomena, causes, factors and developmental rules of landslides, and studied the changes of the strength of landslides and the stability calculation methods from the aspects of slope stability. With the development of modern science and technology, landslides are also involved in a broader area, citing some new methods. As the study of the theory of landslide has been done by the macro
