| 摘 要： | 广布于华南(尤其是香港)地区全风化花岗岩与地质灾害关系密切。其物化指标统计结果以及相互关系研究似很欠缺。通过对香港九龙两处边坡上部3个探坑中48个全风化花岗岩样品物理化学实验结果分析，本文给出了物理化学性质统计值，并对比表面积和阳离子交换容量等主要指标进行了相关分析。这就将物理化学指标问相关关系具体量化，揭示了它们同矿物成分间的关系，并可对化学、物理化学和矿物学实验分析结果进行校验。本文结果对分析其风化特征及其工程地质性质，有一定实际意义。 |

| Abstract: | The completely decomposed granite (CDG), which has close relations with geological disaster, is widely distributed in Southeastern China (esp. in Hong Kong). There are few researches on the statistical values and correlations of the physicochemical parameters. Based on analysis of 48 CDG specimens obtained from 3 trial pits at summits of 2 slopes in Hong Kong, this paper provided statistical values of physicochemical parameters from laboratory tests, and the correlation between surface area and cation exchange capacity. These results quantified the correlation among the physicochemical indices. Furthermore, the relationship between parameters of physicochemical property and mineral compositions was also analyzed. Actually these values are of potential importance to classification of granite weathering and prediction of their engineering geological characteristics. |
| Keywords: | completely decomposed granite physicochemistry cation exchange capacity(CEC) surface area (S) Hong Kong |
