摘要:

分析了目前道面平整度评价中采用的方法、指标及各自的特点,并对其用于道面平整度评价的适用性进行了分析。结合1/4 车模型从原理上推导了道面现行评价方法、指标的评价过程,总结其特点并设想了今后的发展方向。分析了机场道面平整度常见评价方法的原理、技术标准尧优缺点及不同技术指标之间的换算关系,包括三米直尺法、水准仪法尧连续式平整度仪法、递推式纵断面仪法、激光断面仪法、颠簸累积仪法。指出当前的国际平整度指数IRI 在机场道面平整度评价中主要存在其所表征的平整度范围与飞机尺度不协调、无法衡量所有机轮下道面不平整情况所产生的耦合效果2 个缺点。根据上述情况提出了通过建立飞机全尺寸模型研究与民航客机尺度相适应的机场道面平整度评价体系的技术思路。

Abstract:

The methods, indicators and their characteristics of the current pavement roughness evaluation are analyzed as well as their applications. Combining with the 1/4 car model, the evaluating progress of the current pavement evaluation method and indices are derived, their characteristics are summarized and the future developing trend is anticipated. The principles, technical standards, characteristics and conversion between different indices of the current method in pavement roughness evaluation are studied including the three meter ruler method, level instrument method, continuous road roughness meter method, recursive section instrument, laser profilemeter method and bump integrator method. It is pointed out that two shortcomings of IRI(international roughness index), in coordination of the roughness scope with plane scale and incapability of measuring the coupling effect are produced by road surface under all wheels. It is proposed to study the airliner-scale-adapted pavement roughness evaluation system with the airliner scale by the establishment of a full scale aircraft model.

Key words: pavement road engineering, evenness, literature review, 1/4 car model, full scale aircraft model
