摘　　要：介绍了单向格栅软体排结构,设计了单元排体结构连接方法,以及排体结构宽度方向和长度方向的拼接工艺。针对单向格栅软体排结构特征,设计了沉排的施工流程,即宽度方向初步拼接与现场拼接相结合以提高施工效率。结合长江中下游护岸工程的水文资料,对比了单向格栅软体排与连锁排的综合成本,结果表明单向格栅软体排结构具有明显的经济性优势,但其沉排效率不及连锁排结构。The unidirectional grating flexible row structure is introduced,and the unit row structure connection method is designed,as well as the splicing process in the width direction and length direction of the row structure.Moreover,the construction technology is introduced for the flexible mattress composed of unidirectional grille,according to its structural features.That is combining application of the initial splicing with the field splicing in width direction,which is beneficial for improving the construction efficiency.Combined with the hydrological data of the shore protection engineering in the middle and lower reaches of the Yangtze River,the flexible mattress composed of unidirectional grille is compared to the traditional cable-reinforced concrete mattresses.The results show that the former mattresses structure has obvious economic advantages,but its construction efficiency was less than that of the latter mattresses structure.
