| 摘 要： | Red clay is highly silty clay with red and yellowcolors, formed by the weathering and laterization ocarbonate rocks in hot and wet climate condition(Wiesner, 1999; The Committee of the Handbook oGeological Engineering, 1993). Guigang in Guangxis in a low latitude, sub tropical climate, so its sum mer is long and its winter is short, and heat and pre cipitation are profuse. Carbonate rocks are wideldistributed. Given such a geological environment anweathering conditions, …

| Abstract: | There is fine and uniform clay with aluminous and ferrous cementation in the red clay found in Guigang, Guangxi. It has the characteristics of shrinkage outwardly, rigid upper but soft lower and well-grown fissure. In addition there are engineering characteristics such as high water content, low compactness and low compressibility, high strength and high contractility but slight expansibility. This paper discusses the red clay's engineering characteristics and its change regulation with depth by analyzing changes in the red clay's grain size composition, mineralogical constitution, and chemical composition. |
