大金山岛科普码头离海岸线6.2Km,码头最深处地面高程-6m,地形、地质条件及水流条件复杂。本文综合场地地形、地质、水流及海上施工等综合因素,重点从水环境保护角度,对码头及引桥桩基型式进行了分析与合理选择,供类似工程设计、施工参考。 At the distance of 6.2 km from the coastline and at the deepest level of the pier, the pier of Dajin Mountain Island Branch is complex with topography, geological conditions and current conditions. Based on the comprehensive factors such as the topography, geology, water flow and construction at sea, the paper focuses on the analysis of the pier type and the approach type of the approach bridge from the point of view of water environment protection for the similar engineering design and construction reference.
