摘要
针对目前高架桥匝道运营过程中出现的常见病害,结合高架桥匝道结构的力学特性,明确影响高架桥匝道安全性的各种因素,采用层次分析法(AHP)建立高架桥匝道结构的安全评估模型.最后,以五乡互通立交匝道为工程实例,分别对B匝道及E匝道进行安全评估,充分验证了快速路高架桥匝道结构的安全评估体系的可行性和适用性.
For the current existing problems involved in the use of viaduct ramp, various factors affecting the safety of viaduct ramp were clarified based on the study of the mechanical property of the structure of the viaduct ramp. Then the model for safety assessment of viaduct ramp was established according to the analytic hierarchy process（AHP）.Finally,taking Wuxiang interchange ramp as a project ease and evaluating the safety of Ramp B and Ramp E respectively, the feasibility and applicability of the safety evaluation system of expressway viaduct ramp structure was fully verified.
