盐渍土公路工程分类的现状与思考

Present Situation and Review for Highway Engineering Classification of Saline Soil

通过总结和评述国内外盐渍土分类现状,并结合近几年来对盐渍土工程地质专题研究及公路整治工程实践,分析了现行盐渍土公路工程分类中以含盐量作为单一标准来划分盐渍土等级的不合理性,提出以影响盐渍土工程性质的土类、盐分、含水量及温度等指标作为盐渍土公路工程分类指标。

Though summarization and review for highway engineering classification of saline soil at home and abroad, and combined with the study on engineering geology of saline soil and the practice of highway engineering, the unreasonable reasons in Highway Engineering Classification of Saline Soil with single standard of salt content are analyzed. Indexes of highway engineering classification of saline soil are put forward from soil type, salt content, water content and temperature that affect engineering property.
