摘要
U型桥台、扶壁式桥台和轻型、薄壁等实体墩台是中小跨桥梁较常用的下部结构型式,存在的裂缝问题影响整个工程项目的建设质量。利用热弹性力学的基本理论对裂缝的产生和控制进行了分析研究。
U-shaped abutment,counterfort abutment and light or thin-wall solid abutments are commonly-used lower structure types of medium and small span bridges.The existing crack problem can influence the construction quality of the whole project.Based on the basic theory of thermoelasticity,the cause and control of crack are analyzed and studied.
