摘要
根据对正常固结土物理力学性质的分析,得出土的计算孔隙比的计算方法。在对北京地区新近沉积土的物理力学特性分析的基础上,提出利用计算孔隙比和天然孔隙比的对比,对北京地区新近沉积土进行判断的孔隙比鉴别法。该方法只需利用土样的常规室内试验成果,方法简单、有效。勘察中,在现场初步判断的基础上,采用该方法可以对新近沉积土做出更准确的鉴别。
The analysis of physical and mechanical character of normally consolidated soils shows that its void ratio can be calculated roughly. Based on the physical and mechanical characters analysis of recently deposited soils in Beijing region, the void ratio discriminant method which is used to differentiate recently deposited soils by contrast of calculated void ratios and their natural void ratios is provided. All it needs are regular laboratory test results; therefore, this method is simpler and effective. In the geotechnical engineering investigations, based on the field survey and preliminary judgments, this method provides a more veracious way to differentiate the recently deposited soils.
