汉蔡高速公路高液限土作为路基填料的处理技术

Treatment Techniques for High Liquid Limit Soil Sub-grade of Han-cai Highway

以武汉市汉蔡高速公路为例,在完成土工试验的基础上,提出了高液限土的处理方案,比较、分析了各方案的处理效果的经济指标。结果表明,经处理后的高液限土填筑路基的稳定性和耐久性显著提高。

According to the actual project example of the Hancai expressway in Wuhan city, some treatment tech- nologies are adapted to improve the performance of the high liquid limit soil based on a number of laboratorial experi- ments which are carried out to obtain the property of different raw high liquid limit soil samples. The results show that these treatment technologies can improve the stability and safety of subgrade obviously.
