| 摘 要： | 中国东部广泛分布着花岗岩类岩体,经强烈风化作用形成巨厚红色风化壳,其表层残积土的性质与一般流水沉积的粘性土有着明显的差别。通过对北起长春南止湛江14个地区花岗岩残积土的粒度成分、矿物成分、化学成分、物理化学性质、微结构形态、孔隙等特征的深入系统研究,阐明花岗岩的风化机理,揭示了花岗岩残积土的基本特点,分析南方与北方残积土特性的差异,解释了花岗岩残积土强度和胀缩性的本质。

| Abstract: | Granite is vastly distributed in the East of China, a giant layer of red weathered crust is formed after intensively weathering. The properties of surface residual soil is far different from the alluvial cohesive soil. The authors systematizally studied the granularmetric composition, mineral and chemicallcomposition,physical chemistry properties,microstructure and pore fo granite residual soil of 14 places from Changchun to Zhanjiang.The basic characteristizs of residual soil are revealed and the wheathering mechanism of granite is expounded in this paper.The study also explicated the nature of strength,with swelling and shrikage of granite residual soil. |
