摘要
以可拓论为基础,利用现场检测数据,建立了水泥混凝土路面使用性能多维物元模型,考虑脱空这一结构承载缺陷,新增多级加载弯沉轴截距这一指标,选取一组权系数对路面综合技术性能开展可拓评价,并结合现场实际确定新增指标的权系数,结果表明,可拓评价方法有利于获得真实可靠的水泥混凝土路面性能评价结果,具有良好的推广前景。
Based on the extension evaluation theory, the study adopts the field test data, establishes the multi-dimensional matter-element model of the performance of the cement concrete pavement, selects a group of weight coefficients to have the extension evaluation on the pavement com- prehensive technical performance by considering the disengaging of the structural loading shortage and the added muhi-grade loading bending axi- al intercept, identifies the weight coefficient of the additive indexes by combining with the field fact, and proves by the result that the extension evaluation method can be helpful for obtaining the reliable performance evaluation results of the cement concrete pavement, so it has better perspective in future.
