软弱地基条件下桥梁病害检测与分析

Detection and Analysis of Bridge Defects under the Condition of Weak Foundation

针对运营过程中处于软弱地基条件下的桥梁检测,本文依托实际工程项目,通过地形地貌调查、地质勘探、外观病害、工程测量检测和历年病害情况对比,详细描述并分析了软弱地基条件造成的桥台不均匀沉降、开裂、偏位等相关病害成因。分析成果可对后续同类型软基桥梁的勘察设计、施工及养护加固等提供合理的参考。

Aiming at the inspection of bridges under weak foundation conditions during operation,this paper relies on actual engineering projects,through topographic and geomorphological surveys,geological prospecting,appearance diseases,engineering surveys and inspections,and comparisons of past disease conditions,detailed description and analysis of the weak foundation conditions Causes of related diseases such as uneven settlement,cracking,and deflection of the abutment.The analysis results can provide a reasonable reference for the subsequent survey,design,construction,maintenance and reinforcement of the same type of soft foundation bridge.
