摘要
通过桥梁检测、桥下桩基抽芯及抽检桩全孔壁摄像试验等多种尺度研究246省道胥河大桥南岸边坡滑移对桥桩基础稳定性的影响。根据检测结果,评定桥梁技术状况为五类桥,且大桥南岸边坡有整体滑移趋势,建议及时封桥停用,并对南岸进行地质详勘,进一步提出治理大桥病害的工程措施,以策安全。
Through bridge detection,pile foundation loose core and whole wall image inspection,the influence of slope slippage at south bank of Xuhe Bridge along No.246 provincial highway on pile foundation stability is studied.According to the result,technical condition of the bridge is evaluated V class and the whole slope trends to slide.The bridge is recommended out of service for detailed geological survey in order to put forward effective measures to control bridge diseases for safety.
