市桥地区花岗岩残积土工程地质特征和力学性质变化规律

The Engineering Geological Feature and Machanics Character Variation of Granite Residual Soils in Shiqiao Region

广东省和华南地区有着广泛分布的花岗岩残积土是一种特殊地基土。本文根据作者多年来在市桥地区的工程实践和实验室研究,按颗粒级配和力学性质把花岗岩残积土划分为砾质粘性土和含泥质砾砂两亚层,指出了花岗岩残积土的变化规律。

The Granite residual soil,which is widely distributed in Guandong Province, is a special foundation soil. Its engineering geological feature and machanics character have been studied according to author's engineering practice and experiments. It can be divid- ed into two sublayers of gravelly clays and clay-bearing gravelly sands, Its machanics character variation has been illuminated.
