【摘要】：隧道土建结构技术状况直接决定其使用阶段的性能水平,为此,建立一套合理有效的评估方法显得至关重要。当前规范采用最差段落法对隧道土建结构进行评分,为改善规范采用的评分方法,提高土建结构评分的总体性,在深入分析国内外隧道土建结构技术状况评定现状的基础上,按照"普遍反映原则"和"安全原则",提出了基于最差段落评分法的修正方法,细化了隧道土建结构分项与各指标的关系,建立了定性与定量相结合的综合评定标度,实现了规范法中技术状况值与修正法中分项各指标扣分值之间的一一对应关系,得到了一套隧道土建结构技术状况定量评价模型,并结合已有检测评估工程的数据验证了该修正法的有效性。
[Abstract]:The technical condition of the tunnel structure directly determines the performance level of the tunnel structure. Therefore, it is very important to establish a reasonable and effective evaluation method. At present, the worst paragraph method is used in the code to grade the tunnel civil structure. In order to improve the scoring method adopted in the code and to improve the overall score of the civil structure, the present situation of the technical evaluation of the tunnel civil structure at home and abroad is deeply analyzed. According to the "principle of universal reflection" and "principle of safety", a revised method based on the worst paragraph scoring method is put forward, the relationship between the subdivision of tunnel civil structure and each index is refined, and a comprehensive evaluation scale combining qualitative and quantitative analysis is established. The one-to-one correspondence between the technical status value in the standard method and the deduction value of the sub-index in the revised method is realized, and a set of quantitative evaluation model for the technical condition of the tunnel civil structure is obtained. The validity of the modified method is verified by the data of the existing testing and evaluation projects.
