异形构件与半圆体在深水航道整治中的应用

近年来随着长江深水航道整治工程的分阶段实施,半圆体与异形构件在航道整治中得到广泛运用。针对两者的应用异同问题,进行了理论与实际应用研究。从结构形状、结构原理、施工工艺、应用效果及经济性等方面进行对比研究,得出了两者的特点及适用范围。结论是:两者均适用于通常工况下的深水航道整治工程;同等条件下异形构件经济性及耐久性好;半圆体能应对大风浪,应用在大断面堤坝结构有优势。

Application of special-shaped components and semi-circular structurein regulation of deep water channel

Both special-shaped components and semi-circular structures have been widely used in the phased implementation of the Yangtze River deep waterway regulation project.In view of the similarities and differences between them,theoretical and practical research is applied.The characteristics and application scope of the two methods are obtained from the comparative research methods of structure shape,structural principle,construction technology,application effect and economy.The conclusion is that both of them are suitable for deep water channel regulation project under normal working conditions.Under the same conditions,the special-shaped components have good economy and durability, while the semi-circle can cope with the big wind and waves,and the application has advantages in the structure of the large section.
