Fabric of the Simulated Hydraulic Filled Sand and its Variation After Shearing

摘要

In this study, the microanalyses for thin sections of specimens werernpresented. It is shown that the orientation of particle long axis ofrnspecimens prepared by hydraulic transportation tends to be in thernhorizontal direction, while the result in wet tamping specimen is quiterndifferent. Besides, the fabric property is close to that of in situ specimen.rnThe variation of apparent dip angle in vertical section increases slightlyrnafter shearing. However, the major dip angle of the particle long axisrnmaintains in horizontal direction during shearing. The technique andrnthe methodology used in this study can be useful in explaining thernmechanical behavior of the hydraulic filled sand.
