盐渍土公路工程应用对比分析论述

Comparative Analysis of Application of Saline Soil in Highway Engineering

盐渍土作为一种特殊土,其所表现出的工程特性对公路工程有很大的危害。为了分析粗、细粒盐渍土在公路工程中应用的差别,文章先对粗、细粒盐渍土分类与判别的差异进行阐述,然后在归纳总结现有盐渍土研究成果的基础上,分析两者在工程特性及路用方面的不同之处,并结合工程实例加以说明。结果表明,以单一因素为标准对盐渍土的路用性能作出判定存在一定的不足。与细粒盐渍土相比,粗粒盐渍土在公路工程中的应用更为复杂,通过研究分析可为相关工程提供一定的参考价值。

As a kind of special soil,the saline soil does great harm to highway engineering because of its engineering characteristics.In order to analyze the difference of application of coarse grained saline soil and fine particle saline soil in highway engineering,the distinctions of classification and discrimination between coarse grained saline soil and fine particle saline soil are firstly expounded.On the basis of summarizing the existing research results of saline soil,the differences of engineering characteristics and road application are analyzed and illustrated with an engineering example.It shows that there is some deficiency in judging the road performance of saline soil by a single standard.And compared with fine particle saline soil,the application of coarse grained saline soil in highway engineering is more complicated.Through the research and analysis,it can provide some reference value for related projects.
