An empirical equation was proposed to predict compression index (C_c) of saturated reconstituted contaminated clays. Experimental data from 464 oedometer tests from literature were analyzed, aiding to develop a method for predicting the C_c of saturated reconstituted contaminated clays. The predictive capacity of three existing empirical equations of C_c with either liquid limit (w_L), plasticity index (PI) or initial porosity (n₀) was assessed. It was found that these equations previously used for clean soils roughly predict the C_c value of saturated reconstituted contaminated clays. To better predict the C_c, a series of empirical equations were established by regression analysis of the experimental data. Finally, the “best” equation was determined by an assessment of goodness of fit.

提出了一个经验方程来预测饱和再生污染粘土的压缩指数（C _c）。对来自文献的 464 次固结仪测试的实验数据进行了分析，有助于开发一种预测饱和再生污染粘土C _c的方法。评估了具有液限 ( w _L )、塑性指数 ( PI ) 或初始孔隙度 ( n ₀ )的三个现有 C _c经验方程的预测能力。发现以前用于清洁土壤的这些方程粗略地预测了饱和再生污染粘土的 C _c值。为了更好地预测 C _c，通过对实验数据的回归分析，建立了一系列经验方程。最后，“最佳”方程由拟合优度评估确定。
