黔东某机场红粘土工程地质特性及评价

Approach of Ceologic Characteristics and its Evalution of Red Clay in X Airport in Eeast Guizhou

以黔东某机场为例 ,探讨了红粘土的基本物理力学性质及工程地质特性 ,并重点探讨了其承载力 ,胀缩特性、结构特性及评价方法。研究表明 ,场区红粘土具有高含水量、高塑性、低膨胀 ,强收缩、中高压缩性、较高承载力的特性 ,总体上是一种良好的天然地基土。但往往受网状裂隙、厚度分布变化剧烈等影响 ,沉降变形大 ,是一种不均匀的地基。

Red clay is distributed extensive in South China,it is important to our Construct.The basic physical mechanics properties and geological charater of clay are Studied.Bearing capacty swell contraction properties,structure and evalution methods of red day are approached.Red class possesses high water capacity,plastic limit and liquid limit,strive constract med,high condense and higher bearing capacty.It's good nature foundation soil, but it affects by network of cracks and changes of thinkness of soil.It's hi...
