以某简支工字型梁桥为工程背景，对桥梁的病害及成因进行全面检测和分析，得出桥下大方量填土是导致桥墩偏位和墩梁相对位移的根本原因。该桥存在落梁垮桥的危险，对该桥部分危险桥跨的拆除方案进行反复比选和探讨，确定采用安全可靠、经济实用的拆除方案，其可为高速公路桥梁的养护和类似事故处理提供借鉴。

With some simply supported I -beam bridge as project background , this paper detects and analyzes diseases and causes of bridge completely and draws a conclusion that soil filling in large amount under the bridge is primary cause for deviation of piers and relative displacement of pier beams .Since the danger of beam fall and collapse of bridge exists , this paper compares and investigates demolishing schemes for part of dangerous spans in the bridge repetitively and determines adoption of safe , reliable , economical and practical demolishing scheme , this can provide a reference for maintenance of expressway bridges and treatment of similar accidents .
