| 摘 要： | 雷州半岛及海南岛北部,广泛分布着由第四纪玄武岩,风化形成巨厚层的残积红土,其工程地质性质与一般土不尽相同,属地区性特殊土,与该区工程建筑关系密切.本文以野外调查结果及室内试验资料为依据,通过对残积红土的粒度成分、矿物成分、化学成分、物理化学特性、宏观结构、微观结构形态、孔隙特征的全面系统分析,揭示了残积红土的基本特点,阐述其工程地质性质,并对玄武岩残积红土特性进行工程地质评价.

| Abstract: | Quaternary basalt is largely distributed in Leizhou penisula and in the north of Hainan island. The weatering residual deposits are formed thick residual red soil which is different in engineering geology properties from general soil. On the basis of field inspection and testing data from laboreatory, the granuarity composition mineral and chemical composition, physical and chemical properties, macrostructure, microstructure and pore characteristics of the residual red soil have been studed systematically in the paper. Through these researches, the basic characteristics of residual red soil can be revealed. The engineering geology properties of residual red soil also have been analysed. At last the views on the evaluation of engineering geology are put forward. |
