文章回顾了近年米各类土的结构的研究现状和成果.细粒土,特别是粘性土的微观结构最早得到重视和研究,并且实现了从定性研究到定量研究的飞跃.自然界广泛分布的碎石土,其物质组成和结构非常复杂,从"土石混合体"概念提出后,其结构性及工程特性的研究近几年开始成为一个新的热点.钙质结核土具有独特的物质组成和结构特性,应属于区域性特殊土,其工程地质学基础研究基本上还是一片空白.根据目前各类土的结构研究现状及学科发展趋势,文章提出了3个需要重点研究的内容:土的结构数字图像的获取、结构综合性定量化指标的建立及结构性本构模型的建立.
文章迴顧瞭近年米各類土的結構的研究現狀和成果.細粒土,特彆是粘性土的微觀結構最早得到重視和研究,併且實現瞭從定性研究到定量研究的飛躍.自然界廣汎分佈的碎石土,其物質組成和結構非常複雜,從"土石混閤體"概唸提齣後,其結構性及工程特性的研究近幾年開始成為一箇新的熱點.鈣質結覈土具有獨特的物質組成和結構特性,應屬于區域性特殊土,其工程地質學基礎研究基本上還是一片空白.根據目前各類土的結構研究現狀及學科髮展趨勢,文章提齣瞭3箇需要重點研究的內容:土的結構數字圖像的穫取、結構綜閤性定量化指標的建立及結構性本構模型的建立.

This paper reviews the present situation and achievements of the research on the structures of various soils in recent years.The microstructure of fine soil,especially cohesive soil,attracted researcher's attention and was studied early.The advancement and development of science and technology made a breakthrough in the research on microstructure of fine soil from qualitative to quantitative research.The material composition and structure of gravel soil which is widely distributed in nature are very complex.The research on its structure and engineering characteristics has gradually become a new hot issue in the past few years after the concept"rock and soil aggregate(RSP)"was put forward.Cohesive soil with calcareous nodules is one of the regional special soil which has unique material composition and structure.The engineering geological basic research on the cohesive soil with calcareOUS nodules stillleaves a blank.Based on the present situation of the research on the structures of various soils and the discipline development trend,the paper puts forth that the following three contents should be mainly studied:obtaining digital images of soil's structure;finding comprehensive quantitative index of soil's structure:and the foundation of soil structural constitutive models.
