1Micromorphology of landslide soil Case study on the Jibazi landslide in Yunyang in the Three Gorges Region, China显示文摘Landslide is one of natural catastrophes affecting national economy and people’s livelihood There are many reports on the forming mechanism and control of landslide, but the studies on micromorphology of landslide soil are few. There are many potential landslides in the Three Gorges Region in China. In this paper, the micromorphologic features of the Jibazi landslide soil in Yunyang in the Three Gorges Region of the Yangtze River were studied using routine methods, that is, soil micro- morphology, X-ray diffractometer and scanning electron microscope. The main conclusions are as follow: (1) The basic micromorphologic characteristics of the landslide soil are that the fine soil particles are commonly cohesive matrix, finer and lower content o skeleton grains, the microstructures are mainly types of phenocrystal gelatinization, densely chap and fissure structure. As a result, these micromorphologic features affect the discharging of soil water, favor the movement of landslide body and provide an interna basis of materials for the formation of landslide. (2) The concept on the forming material of landslide was proposed, and types of optical beamed clay aggregates Fe-Mn isolates and glassy material were found in landslide-belt soil, which were remarkably differen from the natural soil formation, and had some scientific significance in analyzing the formingmechanism of landslide and distinguishing the landslide-belt soil. (3) Some special micromor- phologic and sub-micromorphologic characteristics, such as fingerprint microstructure, clay beamed bedding microstructure, oppressive microstructure, moulage microstructure and extending hole microstructure, could bring useful micromorphologic evidences for the observation and forecasting of landslide. The results mentioned above will bring helpful micromorphologic evidences for distingui- shing slide soil, analyzing the formation mechanism of landslide, and monitoring and forecasting the occurrence of landslide.HE Yurong CUI Peng LIAO Chaolin ZHANG Baohua ZHAO Yu 2006Journal of Mountain Science2006,3,2:7
2Fractal Characteristic of Soil in Typical Debris Flow-Triggering Region:A Case Study in Jiangjia Ravine of Dongchuan, Yunnan显示文摘The structural features of soil in debris flow-triggering region play an important role in the formation and evolution of debris flow. In this paper, a case study on the fractal of soil particle-size distribution (PSDFs) and pore-solid (PSFs) in Jiangjia Ravine was conducted. The results revealed that the soil in Jiangjia Ravine had significant fractal features and its PSDF and PSF had the same variation trend despite different type of soils in debris flow-triggering region: residual soil (RS)>debris flow deposit (DFD)>clinosol (CL), their fractal dimension of PSDFs are respectively between 2.62 and 2.96, 2.52 and 2.68, 2.37 and 2.52; and the fractal dimension of PSFs are respectively between 2.75 and 2.95 , 2.57 and 2.72, 2.59 and 2.64. The fractal dimension of soil reflected its complexity as a self-organizing system and was closely related to the evolution of soil in debris flow-triggering region.LIAO Chaolin HE Yurong 2006Wuhan University Journal of Natural Sciences2006,11,4:1
