高速公路管理和技术指标的前提、属性分析及方法探讨

Premise, Attribute Analysis and Method Discussion of Expressway Management and Technical Index

针对现行公路管养指标中存在的难点,指出单一指标须满足的可测条件,综合指标属于线性空间,随后得出5个重要属性和构建严谨指标体系的4个原则,并用于构建健康监测指标和桥梁技术状况指标。通过对象、属性分析确定了指标体系,在实际评价中,为解决复杂性问题,采用筛选法获得成功。最后,将此方法推广到隧道技术状况指标和管养行为的评价指标。

Aiming at the difficulties existing in the current highway management and maintenance indicators,this paper points out that a single indicator must meet the measurable conditions and the composite indicator belongs to the linear space. Then five significant attributes and four principles for building the rigorous indicator system are obtained, and are used to construct the health monitoring indicator and bridge technical condition indicator. The analysis on object and attribute determines the indicator system. In the practical evaluation, the use of screening method is successful in order to solve the complexity problem. Finally, this method is extended to the evaluation indicators of tunnel technical condition and maintenance behavior.
