高液限粘土填筑高速公路路基的研究

Experiment Research on Filling Super Highway Bed with High Liquid Clay

针对高液限粘土稳定性差的性质，添加各种外掺剂，研究其混合土料的强度变化规律．采用室内试验分析比较、技术经济指标筛选和试验路段检验的综合分析方法，确定了外掺剂类型和实用的工程配比．研究结果认为，在高液限粘土中掺入4％的石灰所形成的石灰稳定土，达到了实际工程要求．并取得良好的经济效果．

To aim at the stabilized badly character of high liquid clay, the strength change laws of commix clay under mixture ratios were studied in this paped The optimum engineering properties were determined by laboratory test-economic and technical norms-test section of highway. The result indicated that the lime-Stabilized soil of high liquid clay filling 4% lime was appropriate.
