摘　　要：2010年8月19日,修建于清代的石拱桥华阳通济桥发生了垮塌。作者通过大量的走访调查,对该桥进行地理位置、人文环境以及力学分析来初步探讨该桥倒塌的原因。分析结果表明,造成该桥倒塌的主要原因是桥墩基础掏空导致桥墩外侧及拱圈内壁条石失去了传力途径;倒塌前几日的暴雨也是诱因之一。A Stone arch bridge named Tongji Bridge which has been built in Qing dynasty was collapsed in 8.19. 2010. Through a large number of investigations, this paper explores the cause of the bridge collapse by the bridge location, the humanities environment and the mechanics analysis. The analysis result shows that the main cause of the bridge collapse is that the bridge foundation is hollowed so that the stones in the pier lateral and the arch ring wall lose their force transmission route, the rainstorm a few days before the collapse is also one of the reasons.
