摘要
取样会对天然沉积结构性软土产生扰动,使土体的工程性质指标发生改变,取土扰动及其影响研究是软土工程特性研究的重要基础内容。本文首先概述取土扰动机理,总结土样扰动程度定量评价方法并分析其适用条件,随后归纳取土扰动对土体的物理力学指标的影响,探讨并列举室内减小扰动影响的方法,最后提出进一步研究内容的建议。
Sampling will disturb the natural sedimentary structural soft soil,which will change the engineering properties of the soil.Studying the disturbance of soil sampling and its influence is an important basic content of the research on the engineering characteristics of soft soil.This paper first summarizes the mechanism of soil sampling disturbance,summarizes the quantitative evaluation method of soil sampling disturbance degree and analyzes its applicable conditions,then summarizes the influence of soil sampling disturbance on the physical and mechanical indexes of soil,discusses and lists the methods to reduce the influence of indoor disturbance,and finally puts forward suggestions for further research content.
