摘要
某公路简支T梁桥主梁跨中附近底板出现了横向和纵向裂缝,支座附近腹板出现大量的斜裂缝。文章通过荷载试验对该T梁桥的承载能力进行检测,分析其病害原因,采用体外预应力法并对该桥进行加固。
Some horizontal and vertical cracks appeared in the bottom near the mid-span of main girder for a simply supported T-shaped beam bridge, and a large number of inclined cracks occurred in the web near bridge supports. This paper detected carrying capacity of the T beam bridge by load test and analyzed the disease cause. Then the bridge was strengthened by external prestressing method.
