云南某高速公路路堤滑坡形成机理与处治措施研究
|
摘要
针对云南某高速公路路堤滑坡,从地形、地质、地下水和人为因素等方面分析了该滑坡形成的原因及稳定性,并对该滑坡的基本特征提出了4个治理方案进行比选。考虑路堤填料料源较少,在节约造价和不新增取土场的前提下,根据滑坡地形,从相互垂直的两个方向进行弃土反压,同时做好截、排水措施,达到了滑坡治理的目的。
In view of a highway embankment landslide in Yunnan province, the cause of formation is analyzed and the stability of the landslide are conducted from the topography, geology, groundwater and human factors and four control schemes based on the basic characteristics of the landslide are proposed for comparison and selection. Considering that the embankment filling material source is less, under the precondition of saving the cost and not adding the soil field, according to the landslide topography, it carries on the backpressure of the abandoned soil from two directions perpendicular to each other, at the same time, completes the cutting and drainage measures, achieving the purpose of landslide control.
