摘 要: | 钢筋混凝土预制板、梁等构件在多种因素影响下经常会出现裂缝,对裂缝进行修补,使其达到安全使用要求,将是一项费省效宏的工程。该文以湖北竹山县潘口水电站河桥工程T形梁裂缝修补为实例,详细的介绍了修补材料、修补方案、施工工艺以及裂缝修补后T形梁试验检测等内容。检测结果表明,无论是受压还是受拉,该T形梁修补处均无裂缝出现。修补后桥的承载力、结构变形及抗裂标准均达到了技术规范要求,可以交付使用。

Discussion on Patching Measures for Cracks of T-beam of River-bridge |
| |
Abstract: | In practice,it is a useful project with least cost and high benefit to patch the cracks of reinforced concrete units.Here,taking the river-bridge engineering in Pankou Hydropower Station for example,such contents are introduced in detail as the patching materials,patching scheme,construction technology,test checking for the cracks of the T-beam after patching and so on.The results show that after patching,all the bearing capacity,structural deformation and anti-cracking standard of the bridge reach to the requirement of technical codes,and the bridge could be used. |
