墩柱梁板式码头结构在三峡库区的破坏分析

Destructive analysis on pier columned beam-slab wharf structure in Three Gorges reservoir region

大桩柱、大跨度的码头结构是适用于三峡成库后库区中的新型码头结构形式。墩柱梁板式码头结构不仅有利于提高排架间距,同时也能避免大桩柱直接承受船舶的撞击。以重庆市纳溪沟码头为例,针对墩柱梁板式码头结构的力学性能,初步探讨了该结构形式的码头在三峡库区中的破坏形态和裂缝的发展趋势,为该结构破坏模式的研究提供依据。

Large pile and large-span wharf structures are new types of wharf structures which are used in Three Gorges Reservoir region. Pier columned beam-slab wharf structure can increase the space between bent frames. This kind of wharf structure can also protect the large pile from being directly impacted by ships. This paper which aims at mechanical property of pier columned beam-slab wharf structure based on Wharf Naxigou, Chongqing preliminarily investigates the failure mode of the wharf structure and development trend of cracks in reservoir area of Three Gorges. It provides basis for the study of failure mode in pier columned beam-slab wharf structure.
