【摘要】：伴随着我国高等级沥青公路不断建设,大量投入运行的沥青路面早期路面性能衰减甚至破坏现象日趋严重,这与人们对提高路面服务质量的要求相矛盾,因此,在现有技术条件下,通过控制沥青路面施工提高路面性能显得十分必要。本文在对沥青路面施工过程剖析的基础上,运用模糊数学理论,建立了基于性能的沥青路面施工过程控制体系,为保证沥青路面的使用性能提供技术支持。本文主要完成了以下工作:(1)采用因果分析法并结合专家经验,初步确定了沥青路面施工关键质控指标,再通过分析路面性能与施工质控指标的关系,建立了基于性能的沥青路面施工质控指标体系。(2)考虑路面施工的复杂性和模糊性,在基于性能的质量控制指标体系基础上,采用改进的AHP与模糊综合评价相结合的方法,建立了适用于沥青路面施工的模糊综合评价模型。该模型在传统AHP法基础上融入最优传递矩阵,形成改进的AHP法求出指标权重,避免了一致性检验。同时,基于求得的指标权重,结合专家调查的指标集结果,确定各指标隶属度,采用加权求和型算子,得出施工控制体系对施工过程控制的程度,为进一步改进和完善施工过程提供了依据。(3)在相关规范基础上,初步建议了施工控制指标的评价标准;基于模糊综合评判的方法,对路面施工进行事前控制,并举例分析了其实用性;同时,对路面施工事中控制和施工事后控制方法及控制的要点进行了分析,形成了沥青路面施工全面质量控制体系。
[Abstract]:With the continuous construction of high-grade asphalt highway in our country, a large number of asphalt pavement performance attenuation or even destruction phenomenon is becoming more and more serious in the early stage of operation, which contradicts the requirement of improving pavement service quality. Under the existing technical conditions, it is necessary to improve the pavement performance by controlling the asphalt pavement construction. Based on the analysis of the asphalt pavement construction process, fuzzy mathematics theory is used in this paper. A performance-based asphalt pavement construction process control system is established to provide technical support to ensure the performance of asphalt pavement. This paper mainly completed the following work: 1) using causality analysis method and combining with expert experience. The key quality control index of asphalt pavement construction is preliminarily determined, and the relationship between pavement performance and construction quality control index is analyzed. A performance-based quality control index system for asphalt pavement construction is established. (2) considering the complexity and fuzziness of pavement construction, the quality control index system based on performance is established. A fuzzy comprehensive evaluation model suitable for asphalt pavement construction is established by combining the improved AHP and fuzzy comprehensive evaluation method. The model is integrated with the optimal transfer matrix on the basis of traditional AHP method. At the same time, based on the obtained index weight, combined with the result of expert survey, the index membership degree is determined, and the weighted summation type operator is adopted. The degree to which the construction control system controls the construction process is obtained, which provides a basis for further improvement and perfection of the construction process. On the basis of the relevant specifications, the evaluation criteria of the construction control indexes are preliminarily proposed. Based on the method of fuzzy comprehensive evaluation, the pavement construction is controlled in advance, and its practicability is analyzed by an example. At the same time, the paper analyzes the methods and main points of control in pavement construction, and forms a total quality control system for asphalt pavement construction.
