摘要
结合郑西客运专线大体积混凝土预制箱梁的施工实践,介绍了大体积混凝土预制箱梁上拱控制措施,施工实践证明,该控制措施是科学的、合理的和简便的,能有效地保证预制箱梁的质量。
Combined with construction practice of mass concrete prefabrication box beam in Zheng-Xi special railway for passenger transportation, the upwarp control measures of mass concrete prefabrication box beam were introduced. The construction practice proved that the control measure was scientific, rational and simple, and guaranteed prefabrication box beam quality effectively.
