摘要
合六高速公路沿线膨胀土分布广泛,通过现场取样和室内试验分析,得到了膨胀土的矿物成分、基本物性指标及压实特性、膨胀特性及强度等反映其工程特性的综合评价指标,通过击实试验确定了不同击实功条件下弱膨胀土和中膨胀土的最佳含水量,为该地区膨胀土的科学治理提供了可靠的依据.
Expansive siol is distributed widely along He-Liu expressway. The comprehensive evaluating indicators of the expansive soil on engineering characteristics, such as minal components, the basic index of physical appearance, the compacted property, swell-shrink characteristics and strength and so on, are obtained by spot sampling and laboratory tests. The optimum moisture contents of weak and meduim expansive soils are determined under the different compacted power. The reliable evidence is provided for the scientific improvement in expansive soil area.
