【摘要】：分析黄河流域桥梁桩基础损伤的类型及其成因,建立了在役跨黄河桥梁桩基础损伤状况评价指标体系和模糊层次综合评价模型,运用该评价模型对刘江黄河公路大桥进行了损伤状况评价,结果表明:该桥桩基础现有状况等级介于Ⅰ级和Ⅱ级之间,且略微倾向于Ⅰ级,即目前桥梁桩基础存在轻微缺损,但功能较完好,不影响正常使用。该评价模型为黄河流域桥梁桩基础损伤状况的评价提供了客观、合理的评价体系与方法。
[Abstract]:This paper analyzes on the types and causes of bridge pile foundation damage in the Yellow River basin, and establishes the evaluation index system and fuzzy hierarchy comprehensive evaluation model of pile foundation damage of existing bridges across the Yellow River. The damage status of Liu Jiang Yellow River Highway Bridge is evaluated by using the model. The results show that the existing status of the pile foundation of the bridge is between grade I and grade 鈪，
