墩柱梁板式码头结构在三峡库区的推广应用*

针对纳溪沟墩柱梁板式码头的力学性能进行研究,并结合该码头的特点探讨墩柱梁板式码头在三峡库区的应用前景.研究表明,墩柱梁板式码头能够较好地适应三峡蓄水后出现的历时长、水深大现象.该结构形式的码头一方面有利于抬高施工水位,另一方面可以增大排架间距,从而实现码头全天候建设,同时增加了码头结构安全性,其将可能作为库区变动回水段码头的一种新型结构得到推广.

Popularization and application of pier beam slab terminal structure in Three Gorges reservoir

This paper probes into the mechanical properties of slab pier terminal of Naxigou and studies the application prospect of the slab pier terminal in the Three Gorges reservoir. The results show that the slab pier terminal can adapt to the long-duration deep water after the impoundment of the Three Gorges. This kind of structural type can not only improve the construction level, but also increase the bent spacing, so as to realize allweather construction of the terminal and improve the safety of the wharf structure. It will be widely used as a new terminal structure in the fluctuating backwater area of Three Gorges reservoir area.
