Abstract: Through the investigation of such factors relating to the settlement of intermediate piers of simple beam bridges as structural self-weight,vehicle loads, pier deformation, foundation settlement and soil compaction,the paper points out, the main causes for the uneven settlement of intermediate piers,providing useful referencd for the intensifying attention to the pier groundwork

Key words: multi-span simple beam bridges, intermediate piers, uneven settliment, cause analysis

摘要： 笔者通过等跨简支梁桥中墩沉降有关因素结构自重、行车作用、桥墩变形、基础沉降以及土基下沉的分析，得 出了中墩不均匀下沉的主要原因是地基土质状况不同引起的，为加强对基础工程的重视提供了重要借鉴
