【摘要】：涎流冰病害是严寒地区公路病害中危害最大的一种,铜黄高速公路沿线涎流冰病害比较常见。它直接威胁道路行车安全,影响公路的畅通,会产生路面冰毁、翻浆、水毁、龟裂,断板、边坡崩塌、滑坡、剥落,路基失稳、冲刷等公路病害。为此,本文针对近期开工建设的铜(川)黄(陵)高速公路涎流冰病害展开研究,通过工程调查、现场试验和理论分析等方法,对该公路沿线涎流冰病害的成因和形成条件进行了分析,提出治理方案和防治措施。主要包括以下内容:1.对国内外公路涎流冰病害相关资料开展了调研和检索,对铜黄高速公路沿线涎流冰病害进行了实地调查,分析涎流冰病害对路基、边坡、路面造成的危害。2.对现有国内外公路涎流冰病害的成因和防治技术进行了综合评价,分析水文条件、气候气象、地形地貌、地层岩性、路堑开挖及工后养护对公路涎流冰病害形成的影响。3.在现场工程试验的基础上,结合病害成因分析,提出了铜黄高速公路沿线路基、边坡及路面涎流冰病害防治措施,并进行了跟踪观测。4.运用综合模糊评价方法分析了边坡涎流冰病害的治理措施,即边坡渗沟与仰斜式排水孔联合治理边坡涎流冰病害的可行性,并在实体工程进行了验证。
[Abstract]:Salivary ice is one of the most harmful diseases of highway in severe cold area, and it is common along copper and yellow highway. It directly threatens the safety of road driving, affects the smooth flow of highway, and will produce road diseases such as ice damage, slurry, water damage, crack, broken slab, slope collapse, landslide, spalling, subgrade instability, erosion and so on. Therefore, this paper studies the salivary ice disease of the copper (Chuan) Huang (Ling) highway, through engineering investigation, field test and theoretical analysis, etc. The causes and forming conditions of salivary ice disease along the highway are analyzed, and the control scheme and prevention measures are put forward. Mainly include the following content: 1. This paper investigates and retrieves the related data of salivary ice disease in highway at home and abroad, investigates the disease of salivary ice along Tonghuang expressway, and analyzes the harm caused by the disease to roadbed, slope and pavement. In this paper, the cause of formation and prevention technology of salivary ice disease in existing highways at home and abroad are comprehensively evaluated, and the influence of hydrological conditions, climate and meteorology, topography and geomorphology, stratigraphic lithology, cutting excavation and maintenance after construction on the formation of salivary ice disease of highway is analyzed. On the basis of field engineering test, combined with the cause analysis of disease, the prevention and cure measures of salivary ice disease along roadbed, slope and pavement along Tonghuang Expressway are put forward, and the track observation is carried out. In this paper, the comprehensive fuzzy evaluation method is used to analyze the treatment measures of the slope salivary ice disease, that is, the feasibility of treating the slope salivary ice disease by the combination of the seepage ditch of the slope and the inclined drainage hole, and the feasibility is verified in the solid engineering.
