| 摘 要： | 某预应力混凝土连续刚构箱梁桥在运营过程中出现了箱粱顶板纵向裂缝，腹板斜裂缝和横隔板竖向裂缝。通过理论计算对其裂缝病害成因进行了研究，指出这些裂缝病害主要系由行车荷载、温度作用及桥墩沉降等多种原因所致，同时还对其裂缝病害状况进行了评估。

| Abstract: | A prestressed concrete continuous rigid frame box beam bridge produced three main kinds of crack in the operation process,which are the longitudinal crack in the bottom of the top flanges,the slanting crack in the web and the vertical crack in the diaphragm.Through the theoretical calculation this article researched on the cause of the cracks,and pointed out that these crack diseases appear mainly due to the driving load,temperature effect and pier's subsidence.At the same time this article has also carried out the appraisal of the crack disease condition. |
