高速公路桥墩基础灾后工作状态检测与评估

Post-disaster Inspection and Assessment of Working Condition of Expressway Bridge Pier Foundation

桥墩基础工作状态检测与评估一直是工程技术人员面临的一个难题。本文以一受灾的高速公路桥墩基础为研究对象,根据桥墩基础灾后最终状态及处治情况,采用无损检测和仿真计算的方法,对桥墩基础灾后和灾害处治过程中的受力状态进行了分析。无损检测结果与仿真计算结果基本一致,且探查结果表明检测评估结果与实际情况基本吻合。

Inspection and assessment for working condition of bridge pier foundation is a difficult problem faced by engineers and technicians.A certain pier foundation post-disaster was cited as an example and studied in this paper.According to the final state of bridge pier foundation post-disaster and its treatment situation,by using the method of non-destructive test and numerical simulation,the mechanics state of the bridge pier foundation post-disaster and during disaster treatment process were analyzed.The results of non-destructive testing are basically agree with the results of numerical simulation.The assessment results are basically consistent with the actual situation.
