摘要
为有效进行部分滑塌的膨胀岩土路堑边坡防护,以一具体的膨胀土质与岩质路堑段为对象,通过钻探研究边坡的工程地质及土性特征,针对其征地特别困难及未滑塌边坡的岩土层相对完整的特点,提出了对滑塌部分进行土工格栅柔性支护,对未滑动部分采取土工格室柔性支护的综合处治方案。工程实施表明,该方案能经济有效地解决部分滑塌路堑膨胀土边坡问题。
In order to effectively protect partly slumped expansive rock and soil cut slope, a given cut section of expansive soil and rocks is taken as study objective, and the geological and earth characteristics of side slope are studied through drilling. In view of hard land acquisition and relatively complete geotechnical layers of non-slipped slope, it is proposed that geogrid flexible support is adopted for slipped part and the non-slide part is treated by the geocell flexible retaining. The engineering practice shows that this solution can effectively solve the problems for locally slipped slope of expansive soil.
