摘要
针对合六高速公路沿线膨胀土分布广泛的现状,通过大量的现场调查和室内试验,获得了膨胀土的基本物性指标和工程特征参数,结合国家技术规范对膨胀土路堤边坡稳定性进行了分析和计算,得到了不同坡比条件下边坡的稳定系数,提出了路堤边坡的处治措施,为护坡设计提供了依据。
Expansive soil is distributed widely along He-Liu expressway. The basic indicators of physical appearance and the parameters of the expansive soil on engineering characteristics are obtained through amount of sampling and indoor tests. The stability factors of slope are analysized and calculated combining with the state technical specification under the different slope gradient. The treating measures are put forward about the embankment fill. The basic is provided for the slope design in expansive soil area.
