摘要
湖南省南县至益阳高速公路沅江—资阳段广泛分布第四系更新统(Q2)网纹红土,该类土的分布具有普遍性和区域性。为全面了解其工程特性,结合工程地质调绘、钻探、原位测试、土工试验、数值模拟分析等手段,对网纹红土的成因、物理性质、强度及变形、膨胀性等工程特性进行试验研究,为判断网纹红土作为高速公路路基填料的适宜性及路堑边坡坡比选取等提供参考。
There widely spreads reticulate red clay of Quaternary Pleistocene （Q2） series in Yuanjiang and Ziyang sections of Nanxian-Yiyang Highway in Hunan Province. The distribution of such soil has universality and regionality. To understand its engineering characteristics, the paper, by means of engineering geological mapping, drilling, in-situ testing, soil test, numerical simulation and other analysis, made experimental study on this soil＇s gensis, physical property, strength, deformation, expansibility and other engineering characteritics, thus provided a reference for the adaptability of judging reticulate red clay as highway subgrade fill and the availability of selecting cutting slope＇s gradient in certain interval.
