摘要
通过体外预应力+碳纤维布加固前后试验,对试验梁加固前后各级荷载作用下控制截面的应变、位移和裂缝宽度进行详细加载测试。试验结果表明体外预应力+碳纤维布加固法能够有效降低开裂结构控制截面的应变、挠度和裂缝宽度,提高结构刚度和耐久性,延长桥梁使用寿命。可为今后类似工程的加固设计提供参考。
Through the external prestressed + carbon fiber cloth reinforcement before and after the test,this paper carried out the detailed loading test of controlling section strain, displacement and the crack width before and after the test beam reinforcement under various loading.
