1976年唐山大地震波及天津、塘沽地区,对该地区的板梁式、无梁面板式高桩码头造成不同程度的破坏;按码头损坏程度可分为完好或基本完好、中等破坏、较严重破坏和严重破坏四种类型。本文从调查码头实际震害出发,综合分析了地基土、岸坡、桩台结构本身以及桩台下桩帽和基桩在地震作用下对码头建筑物安全的影响,可供进一步改善板梁式、无梁面板式高桩码头的抗震设防参考。
The Tangshan earthquake in 1976 affected areas of Tianjin and Tanggu, which caused different degrees of damage to the plate girder and beamless panel piled wharf in this area. According to the degree of wharf damage, it can be divided into intact or basically intact, moderately damaged and severely damaged And severely damaged the four types. Based on the investigation of the actual seismic damage of the wharf, this paper analyzes the influence of the foundation soil, bank slope, the structure of the pile platform and the pile caps and piles under the earthquake on the safety of the wharf buildings, which can be used to further improve the plate beam Seismic fortification reference for beamless piled piled wharf.
