摘　　要：基于石灰改良膨胀土的机理,通过分析EDTA法测定不同处理环境下石灰土消耗EDTA二钠标准溶液量的不同,得出:石灰土中存在"时温等效"性,同时再次证实石灰土灰剂量测定结果受温度和含水量的影响较大。Based on the mechanism of lime-modified expansive soil, the EDTA method was used to determine the difference in the amount of EDTA disodium standard solution for lime soil consumption in different treatment environments. It is concluded that there is also a ＂time-temperature equivalent＂ effect in the lime soil, and it is confirmed again that the lime dosage measurement results in lime soil are greatly affected by temperature and water content.

关 键 词：石灰土 石灰剂量 时温等效
