摘要
膨胀土胀缩性能大,吸水膨胀软化,失水收缩硬裂,国内很多膨胀土路堑边坡出现滑坡、坍塌等现象,本文结合河南省南阳-邓州高速公路膨胀土路堑段,因地制宜的提出防止膨胀土边坡溜坍和滑坡等病害的边坡设计、施工技术和控制标准。
Expansive soil is a kind of soil which will expand with enough water and will shrink without water, so it has caused a lot of damage in the road slope. In order to protect the side slope in the expansive soil, the essay puts forward the design of side slope and the analysis of construction technology on the basic of the slope of Nanyang - Dengzhou Freeway in Henan province. Through which we can prevent the diseases such as land side by the design, the construction technology and the controlling criterion of the expansive soil.
