摘要
针对广梧高速公路高液限土的不良特性,进行了一系列室内试验,测试土样的物理力学指标;借助聚类分析理论,对样本土样进行分类,并确定各类的属性特征值和改良方案;根据土样与属性特征值的相关距离确定各类土样的改良试验项目。以新土料改良方案确定过程为例,介绍了研究结论的使用过程。
Against the bad properties of high liquid limited soil of Guangzhou-Wuzhou Highway,a series of indoor experiments is carried out to test the soil sample＇s physical mechanics indexes;depending on the cluster analysis theory,the soil samples are classified and the various feature values and improvement programme are confirmed;then the testing items of soil improvement are defined according to the correlation distance of the soil sample and the feature values.Taking the determining course of improvement programme of new soil material as the example,the application of research conclusion is introduced.
