土石混合体研究现状及发展趋势
Research status and development trend of soil-rock mixture
摘要
Abstract
Based on research data on soil-rock mixtures at home and abroad, the research status of soil-rock mixtures was analyzed in terms of meso-structure properties, shear strength properties, macro-elastic parameters, permeation properties, the relationship between meso-structure properties and shear strength properties, and the numerical tests of meso-mechanics of soil-rock mixtures. The deficiency of studies of physical and mechanical properties of soil-rock mixtures were summarized and its development trend was also analyzed on the basis of the research status of soil-rock mixtures. An interdisciplinary technology integrating geology, geometry, computational science, image processing technology, and morphology was used to three dimensions reconstruct and to randomly generate the meso-structure of the soil-rock mixture. The numerical structural model and new laboratory equipment applicable to the complex geotechnical media should be developed. The macroscopic deformation and failure mechanisms of soil-rock mixture should be studied in-depth at meso-structure level and the trend of development should move toward the establishment of a structural constitutive model.关键词
