摘要
从工程实例出发,分析了后张预应力混凝土梁锚下混凝土裂缝产生的原因和处理方法。并对“公路钢筋混凝土及预应力混凝土桥涵设计规范JTGD62-2004”中有关“局部承压”计算公式进行了探索和讨论。
By the engineering example,the reason and the treatment method of the concrete crack under anchorage device of post-tensioned concrete beam are analyzed.The local pressure formulas of Code for Design of Highway Reinforced Concrete and Pre-stressed Concrete Bridges and Culverts JTG D62-2004 are probed.
