本文是研究湿陷性黄土地基经强夯后(自原地面算起)消除黄土湿陷性的有效深度。为了建立强夯变量(夯锤重量W、落距H、夯锤底面积的半径r、夯击次数N、土的干容重γd和含水量w)与消除黄土湿陷性的有效深度之间的关系,作者做了黄土强夯的室内模型试验,取得强整变量与消除湿陷性的有效深度有关的各项数据,同时也收集了现场强夯试验的各项数据,应用统计分拆,得到了估算消除湿陷性的有效深度的经验公式。 This article is to study the effective depth of collapsible loess foundation after removing the loess (calculated from the original ground) to eliminate collapsibility of loess. In order to establish a strong enthalpy (W hammer weight W, drop distance H, radius r of ramming hammer area, number of slamming N, dry bulk density γd and water content w) and the effective depth to eliminate loess collapsibility In the relationship, the author conducted an indoor model test of the loess dynamics and obtained various data relating to the consolidation of variables and the elimination of the effective depth of collapsibility. At the same time, the data of the field strength test were also collected and statistically separated. An empirical formula for estimating the effective depth to eliminate collapsibility.
