摘    要:该文选取公路经过区域有代表性的膨胀土土样,在实验室对土样的一些常用工程指标进行反复的循环试验,揭示了膨胀土或其与普通土的混合土在反复干湿作用下所具有的变化规律,可为膨胀土地区修建二级公路时修筑、处治路基提供依据及参考。

关 键 词:干湿循环  膨胀率  膨胀力  CBR

Abstract:The article takes the representative expansive soil example of the areas where the highway passes and carries out the repeated circle test of some common engineering indexes of the soil example in the laboratory.The test result reveals the varying laws of the expansive soil or its mixed soil with the normal soil under the dry and moist actions,which can provide the basis and reference for building and treating the roadbed of ClassⅡhighway constructed in the expansive soil areas.
Keywords:CBR
