为了揭示连续配筋混凝土路面水损破坏的内在机理,设计一种连续配筋路面裂缝渗水速率的模拟试验方法,用于分析连续配筋混凝土路面裂缝渗水规律。通过试验测试了连续配筋混凝土路面不同裂缝宽度的渗水速率,并拟合了两者之间的数量关系,结果发现渗水速率随裂缝宽度的增大而急剧增加,两者大体呈二次递增关系。试验结果表明,裂缝宽度对渗水速率相当敏感。实际工程应用中,为了减少连续配筋混凝土路面的水损破坏,在设计上应根据降雨量大小,采取适当的防水措施和设计方法,如采用主动诱导切缝并做封缝处理,或在设计时选用更小的裂缝宽度,以提高其路用品质,发挥连续配筋混凝土路面长寿命优势,保证长期使用性能。
In order to reveal the inherent mechanism of water damage damage of continuous reinforced concrete pavement, a simulation test method of water penetration rate of continuous reinforced pavement crack was designed to analyze the law of seepage of cracks on continuous reinforced concrete pavement. The seepage rate of different widths of continuous reinforced concrete pavement was tested through experiments and the quantitative relationship between them was fitted. It was found that the water seepage rate increased sharply with the increase of the crack width, and the two generally increased in a second order . The experimental results show that the crack width is quite sensitive to water infiltration rate. In practical engineering applications, in order to reduce the water damage of continuous reinforced concrete pavement, proper waterproofing measures and design methods should be adopted according to the amount of rainfall in the design. For example, the use of active induced kerf and sealing treatment, or in the design When using a smaller crack width, in order to improve their road quality, continuous reinforcement of concrete pavement to play long-life advantage, to ensure long-term performance.
