| 摘 要： | 土石混合体是一种特殊的工程地质材料,其非均质、非连续和非线性特征决定了土石混合体变形破坏及细观机理的复杂性,常规岩土力学的试验方法和分析理论难以应用.目前土石混合体变形破坏研究尚不深入,特别是对细观机理以及定量描述方法缺乏足够的认知,未形成系统的实验方法和理论分析体系.从现场原位试验、室内试验、结构模型和数值分析4个方面对国内外近些年来土石混合体研究进展进行综述,分析了目前研究存在的困难与挑战,探讨了未来发展方向.

| Abstract: | Rock-soil mixture （RSM） is a unique type of geomaterials with distinct heterogeneity, discontinuity and nonlinearity, causing the complicated behavior and mechanism of deformation and failure. As a result, the testing methods and analytical theories of the conventional geomechanics can barely apply to RSM regarding its complexity. Nowadays, few comprehensive testing methods and analytical theories are available due to the lack of knowledge of the intrinsic mesomechanisms and the characterization of deformation and failure of RSM. This paper reviews the major progresses in the research of RSM from four aspects： in-situ tests, laboratory tests, structural models and numerical analyses. The existing difficulties and challenges, future work and prospective directions of the research are discussed in the paper. |
