随着混凝土梁桥的不断推广和应用,在公路、铁路项目建设中出现了预应力简支梁、连续梁以及连续刚构等桥梁结构形式。该类梁桥在施工和使用过程中或因质量问题或因处置不当致使出现了许多裂缝,影响梁桥美观,更有甚者影响到使用功能。作为工程技术人员,如何做好裂缝成因分析和预防对策尤为重要。 With the continuous popularization and application of concrete girder bridges, prestressed simply supported girders, continuous girders and continuous rigid girder bridges have appeared in the construction of highways and railways. This type of beam bridge during construction and use or due to quality problems or due to improper disposal caused many cracks, affecting the beam bridge beauty, what is more, affect the use of function. As engineering and technical personnel, how to crack the cause of formation and prevention is particularly important.
