摘要
依据南水北调中线一期工程前期勘察资料并结合试验成果,介绍并分析了南阳盆地膨胀土的生成环境、宏观特征及与膨胀土类别的相关性,提出了膨胀土现场快速判别与分类的方法及验证的物理力学指标,同时指出在膨胀土的判定与分类时应紧密结合工程类型进行,为南水北调中线一期工程南阳段膨胀土现场判别与分类提供了依据,亦可作为膨胀土地区工程地质勘察与施工的参考.
By combining the experiment result and the investigation data of the Phase I of Middle Route Project of the South-to-North Water Transter,we gain a further acquaintance with the expansive soil in Nanyang Basin,including its growth environment,its macro-characteristic and the classification.Then a method for in-situ identification and classification of the expansive soil in a short time is presented and some physico-mechanical properties are given to check so as to provide a basis for identification and classification of the expansive soil in Nanyang basin.At the same time,we suggest that the identification and classification of the expansive soil should be combined with the engineering type closely.This paper can also be used as a reference for engineering geological investigation and construction in expansive soil areas.
