| 摘 要： | 文章通过调查大量的U型桥台的健康情况,分析病害形成原因.并以昌樟高速破江小桥为例,采用有限元软件模拟破江小桥U型桥台在运营荷载作用下的应力场和位移场,分析认为台背内土压力和桥上压力共同作用使U台墙内产生较大的拉应力导致混凝土U型桥台开裂.

| Abstract: | Based on the investigation of U type abutment crack,the crack factors of U type abutment crack are analyzed.Taking the U type abutment of Changzhang highway as an example,where the stress and strain of the U type abutment under the work loads are simulated,this paper comes to the conclusion that the crack problem of the U type abutment can be attributed to the joint work of the soil stress and bridge stress. |
