道路翻浆的原因和处理措施方案.doc

白城师范学院本科毕业论文 . . . PAGE 8 - - 摘要 道路翻浆，是指路段上因土的特性、季节性水分的运移及气候的影响，而引发的弹簧状态。道路翻浆现象是处在一年四季之中的，水分因为不同季节而产生不同的运动状态，在冬季冻胀与春季融化之后，对路面产生弹簧、鼓包、泥浆、裂缝等现象。在我国，尤其以北方地区与西藏等地，因为受到季节气候，以及冻土的影响，道路翻浆现象比较严重，这对这些地区的交通运输造成了巨大损失。目前，在国内外对于冻土及道路翻浆的研究的基础上，我国已经在冻土领域迈出了一大步，但是道路翻浆的形成机理机理与防治、养护措施，仍是我们日后对于北方及西藏地区公路研究的主要方向。笔者在国内外研究成果的基础上，对道路翻浆的原因及主要形成条件进行简要的分析，并提出道路翻浆的养护、防治措施。 关键词　道路翻浆；翻浆机理；防治养护 Abstract Frothing refers to affect the characteristics of the soil on the road due to seasonal moisture migration and climate caused by spring state. Frothing phenomenon throughout the year among the water because of the different seasons have different state of motion, in the spring after the winter frost and thaw of pavement spring, the phenomenon of drum kits, mud cracks in. In our country,?especially in the?northern region and?Tibet,?because of?seasonal climate?and permafrost?effects of?road frost boiling?phenomenon is quite serious,?which of these regions transportation?caused huge losses. At present, at home and abroad for study of permafrost and Frothing on the basis of permafrost areas in China has taken a big step, but the mechanism of the formation mechanism Frothing and control, conservation measures, we are still in the future for the northern and the main direction of research in Tibet highway. The author on the basis of domestic and foreign research results, for the reasons and the main road Frothing brief analysis of the formation conditions and proposed conservation, prevention of road Frothing.
