摘要/Abstract

摘要： 对以连云港地区的海相软土为原料的水泥土进行了一系列物理、强度试验，分析了含水量、水泥用量和龄期对水泥土强度的影响，提出了似水灰比的概念用于水泥土强度的预测。采用提出的水泥土强度预测公式，根据某一似水灰比、龄期28 d某种的水泥土室内试验强度，可以预测不同含水量、不同水泥用量和不同龄期的水泥土室内试验强度。通过比较分析发现，得出水泥土强度预测公式可以很好地应用于其他研究者已经发表的水泥土试验数据，进一步验证了所提出的强度预测公式的有效性。

Abstract: A series of physical tests and unconfined compressive shear tests were performed on reconstituted Lianyungang clays mixed with powder cement or slurry cement to investigate the effects of water content, cement content and curing time on the strength behavior of the cemented clays. A concept of quasi-water-cement ratio is proposed for predicting the unconfined compressive strength of cemented clays. The strength prediction formula proposed in this study can be used for predicting the change in unconfined compressive strength with the variation of water content, cement content and curing time, based on the laboratory test result of the cemented clay with 28days of curing time for only a given quasi-water-cement ratio. The proposed strength prediction formula can be also well applied for the test data of the cemented soils published by other independent researchers, further indicating the validity of the strength prediction formula.

Key words: strength prediction, quasi-water-cement ratio, cemented soils, curing time, liquid limit
