纵观近几年我国公路上修建的高等级大、中桥梁发现,几乎都采用先简支后连续结构体系。现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。 Looking at the high-grade large and medium-sized bridges built in our country’s roads in recent years, we have found that almost all of them adopt the system of simple support and continuous construction first. The advantages and the main points of the construction process of the first simply supported continuous structural system in the actual project are described. The simple and easy process technology used in the construction process is discussed. Finally, the quality control opinions of the construction of the first simple supported continuous bridge are proposed.
