摘要
通过对几座高填方U型桥台在侧墙相接处由上向下开裂现象分析,认为是由于U型桥台构造本身的缺陷、持力层的变形、施工不合理等原因造成了U型桥台开裂,提出了合理的处理方法,并针对以后设计、施工此类结构提出了对开裂U型桥台加固处理的建议。
Through the analysis of the cracking in the side wing of high fill mason U-type bridge abutment, discussion is made on the eases that include the structure limitation, distorted bearing course, and improper construction, and provided the countermeasures.
