| 摘 要： | 昔格达地层的沉积地质历史环境决定了昔格达地层的多旋回性及其中泥岩的近饱和特性 ,因此昔格达土填料具有一般其他岩土填料不一样的工程特征。本文通过对昔格达土工程特性的论述 ,以含水量为锲入点 ,分析了含水量变化对昔格达土填料工程性质的影响 ,得出昔格达土混合填料最大干密度 dmax、压实度及强度c、 值都与含水量存在一致的相关性 ,即存在一个最优含水量 ,这个最优含水量接近随机混合的昔格达填料的天然含水量的结论。

| Abstract: | The multi-cyclicity of Xigeda stratum and near-saturation of mudstone within it, which resulted from the sedimentary environment, lead to its engineering characteristics different from other soils. In this paper, authors first characterized moisture content of Xigeda stratum, and then evaluated its effect on engineering properties of soil. At last, it was concluded that uniform correlations exist between moisture content and the four engineering property indexes; maximal dry density ( d max ) ,compacting degree (K), and shear strength parameters (c、) in Xigeda stratum. It was also found that the optimal moisture content is close to natural moisture content of the randomly mixed Xigeda fill. |
