摘　　要：钢抱箍支撑体系因其具有加工简单、施工方便等特点,近年来被广泛应用于不宜采用支架法或地基承载力差的环境下的桥梁盖梁支撑体系。鉴于宏波码头上部现浇混凝土梁板结构处于长江高水位施工,其周边环境复杂、工期十分紧张,导致原混凝土基础和满堂支架法不具备施工条件。通过方案比选后最终选用了钢抱箍和型钢支撑体系,满足了现浇混凝土梁板结构耗时短、施工方便的要求^([1])。所取得的经验可为今后在高水位或基础承载力差等受限空间时的工程建设参考。Steel hoop support system has the characteristics of simple processing,convenient construction.It has been widely used in recent years in bridge cap beam support systems in environments where the bracket method is not suitable or the foundation bearing capacity is poor.In view of the fact that the cast-in-place concrete beam-slab structure of the upper part of Hongbo Wharf is under construction at high water level of the Yangtze river,its surrounding environment is complex and the construction period is very tight,resulting that the original concrete foundation and the full support method are no longer suitable for the construction.After comparing the solutions,the steel hoop and support system are finally selected,which can meet the requirements of short time consumption and convenient construction of the cast-in-place concrete beam-slab structure[1].The experience gained can provide a reference for future engineering construction in restricted spaces such as the high water level or poor bearing capacity of foundation.
