| 摘 要： | 现浇箱梁应用广泛，但多数箱梁在营运后，出现了纵向裂缝、竖向裂缝、混凝土破损、露筋等一系列病害，缩短桥梁的使用寿命。通过对嘉兴某高速枢纽内营运现浇箱梁的病害归纳和总结，分析其产生的原因，提出了应严把设计关，加强施工过程的质量监督等措施，从源头上阻截箱梁产生病害。

| Abstract: | Cast - in - place box girders are widely used nowadays, however, most of which see a host of damages in the operation, including longtitudinal cracks, vertical cracks, concrete damage, exposed reinforcing bars, etc., shorten- ing the service life. This paper, based on the surnrnary from analyzing the damages of cast - in - place box girder in one of the expressway hubs in Jiaxing （located in Zhejiang Province in East China）, digs into the reasons, proposing that strict design, quality supervision in construction shall be implemented to prevent the damages from the very beginning. |
