Abstract

The study focused on the influence of various engineering factors on the strength of rigid airport pavement. Based on different test schemes, we established indoor and outdoor tests, compared the strength test results, and quantitatively analyzed the impacts of mechanical damage, maintenance conditions, and construction technology on the splitting strength of rigid airport pavement. We further fitted the correction coefficients of the splitting strength of core samples with different height-diameter ratios. Dempster-Shafer (D-S) evidence theory and gray correlation analysis were used to analyze the correlation between the influencing factors and the pavement splitting tensile strength. The importance of the factors affecting the rigid airport pavement strength was then determined. The results showed that the loss rates of pavement splitting tensile strength caused by differences in construction technology, curing conditions, and mechanical damage were 6.90%, 4.43%, and 2.11%, respectively. The correlation between each influencing factor and pavement tensile strength was good. The degree of influence decreased in the following order: construction technology > curing conditions > mechanical damage. These findings can help the reasonable allocation of resources on construction sites.
基于 Dempster-Shafer 证据和灰色关系的机场路面强度评估
研究了各种工程因素对机场刚性路面强度的影响。基于不同的试验方案,建立室内和室外试验,对比强度试验结果,定量分析机械损伤、养护条件、施工工艺等因素对机场刚性路面劈裂强度的影响。进一步拟合了不同高径比岩心试样劈裂强度的修正系数。采用D-S证据理论和灰色关联分析法对影响因素与路面劈裂抗拉强度的相关性进行了分析。确定了影响机场刚性路面强度因素的重要性。结果表明:施工工艺、养护条件和机械损伤差异造成的路面劈裂抗拉强度损失率分别为6.90%、4.43%和2.11%;各影响因素与路面抗拉强度的相关性较好。影响程度依次为:施工技术>;养护条件;机械损伤。这些发现有助于建筑工地资源的合理配置。
