摘要: A field investigation of the Huangtupo landslide in Three Gorges Reservoir area, China, indicated that particle-size distribution—characterized by an index termed fractal dimension—varied along main sliding direction: dimension tended to increase this direction. preliminary study spatial variability slip zone based upon was performed. Remolded soil samples with various dimensions obtained from were prepared for laboratory testing carried out determine effect on micro and macro behavior soils. The microstructure each sample determined using scanning electron microscopy, while its macromechanical properties evaluated via consolidated undrained triaxial tests. results showed there close relationships microstructure, stress–strain behavior, shear strength. test also consistent landslide. Thus, can be used as indicator a
