摘要
研究整理了软土微观结构特征试验分析的技术要点,分析软土蠕变试验与孔隙数、复杂度和概率嫡之间的关系,总结软土宏观力学性质与微观结构特征的响应规律,得出以下结论:(1)采用微观参数建立的软土结构性关系式对研究微观参数与宏观蠕变力学关系是可行的;(2)分类阐述了不同蠕变试验对蠕变破坏前后软土微观结构参数的影响;(3)提出基于函数关系式将微观结构分析试验与宏观力学特性试验相结合的方法,开展软土结构性参数指标与软土宏观力学性质相关性的试验研究。
This study sorts out the technical points of the experimental analysis of soft soil microstructure characteristics,analyzes the relationship between soft soil creep test and pore number,complexity and probability entropy,and summarizes the response law of macroscopic mechanical properties and microstructure characteristics of soft-soil.(1)The soft-soil structural relationship established by microscopic parameters is feasible for studying the relationship between microscopic parameters and macroscopic creep mechanics.(2)The classification describes the microstructure of soft-soil before and after creep damage by different creep experiments.The influence of parameters.(3)The method of combining the microstructure analysis test with the macroscopic mechanical property test based on the functional relationship is proposed,and the experimental research on the correlation between the structural parameters of soft soil and the macroscopic mechanical properties of soft-soil is carried out.
