基于大量调查资料,归纳出了黄土路堑高边坡的8类地质结构模型。以“宽台陡坡”的设计思路,通过对不同坡型下黄土路堑高边坡的稳定性及应力应变分析,提出了按工程地质区推荐的公路黄土路堑高边坡坡型设计方案。该方案已在陕西省已建和在建高速公路黄土路堑高边坡设计中得到应用,取得了良好效果。同时,对黄土地区的其他省区公路建设具有参考价值。
Based on a large number of survey data, eight types of geological structure models of loess cut high slope are summarized. Based on the design concept of “wide terrace and steep slope”, this paper presents the design scheme of high side slope of highway loess cut recommended by project geology area through the analysis of stability and stress-strain analysis of high slope under loess slope. The scheme has been applied in the design of high slopes of loess cuttings of the existing and under construction of Shaanxi Province and has achieved good results. At the same time, it is of reference value to the highway construction in other provinces and regions in the loess area.
