摘要
预应力混凝土T梁在我国高速公路桥梁中使用广泛,T梁结构出现裂缝将影响整体梁桥的使用功能。结合两个典型的工程实例,分析了T梁在预制过程中和在运营过程中发生裂缝的原因和控制措施。
Pre-stressing concrete T-beam is widely used in our expressway bridges,but cracks in pre-stressed concrete T-beam will influence the using function of the whole bridge.Combined with two engineering practice,the causes and control measures of cracks during prefabrication and operation are analyzed.
