板梁桥在高桩码头接岸结构中的应用

摘要

由于受港区岸线规划等条件的限制，天津港某高桩码头的前沿线距后方吹填围埝仅50.0 m左右。在码头承台后方接岸结构的设计中综合考虑工程投资、工期和施工条件等方面的因素，经多方案比选最终选用板梁桥方案有效压缩了接岸结构宽度。该方案既能满足规划要求，又方便施工和后期使用，在节省投资和确保工期方面效果明显。%Being restricted by harbor's shoreline layout, the front line of one piled wharf is only 500m far from rear cofferdam in Tianjin Port. Project investment, construction period and conditions are fully considered in the design of shore approaching structure, which is located in the rear of the wharf's platform. By comparing different options, plate-girder-bridge is eventually selected, which effectively reduces the width of shore approaching structure. The option not only satisfies the demand of harbor's layout, but also facilitates the construction and regular use. In addition, it guarantees the construction period and saves the investment.
