近几年,随着公路桥梁的技术发展,先简支后连续的桥梁结构形式逐渐推广,我国公路上修建的高等级的大、中桥梁发现,几乎都采用先简支后连续结构体系。本文阐述了先简支后连续结构体系在实际工程中的优点和施工工艺要点,探讨了施工过程中采用的简便易行的工艺技术,最后提出先简支后连续桥梁施工的质量控制意见。
In recent years, along with the technical development of highway bridges and bridges, the first form of continuous bridge structure after simple support has been gradually popularized. Most large and medium-sized bridges constructed on the highways in our country have found that almost all of them adopt the simple supported and continuous structural system. This paper describes the advantages of the simple supported post-continuous structural system in practical engineering and the key points of the construction process, discusses the simple and easy process technology used in the construction process, and finally puts forward the quality control opinions of the construction of the first simple supported continuous bridge.
