针对跨海大桥浅水区承台施工,通过对钢吊箱围堰、拉森Ⅳ型钢板桩围堰和新型钢板桩围堰的分析对比,在省道263南北长山联岛大桥承台施工中采用了新型钢板桩围堰,该钢板桩围堰结构简单、设计新颖、受力明确、稳定可靠,具有较强的抗风浪能力和较高的安全和稳定性,确保了承台和墩身的顺利施工,保证了承台和墩柱的施工质量,可为强风浪频发海域的海上桥梁施工提供参考和借鉴。
針對跨海大橋淺水區承檯施工,通過對鋼弔箱圍堰、拉森Ⅳ型鋼闆樁圍堰和新型鋼闆樁圍堰的分析對比,在省道263南北長山聯島大橋承檯施工中採用瞭新型鋼闆樁圍堰,該鋼闆樁圍堰結構簡單、設計新穎、受力明確、穩定可靠,具有較彊的抗風浪能力和較高的安全和穩定性,確保瞭承檯和墩身的順利施工,保證瞭承檯和墩柱的施工質量,可為彊風浪頻髮海域的海上橋樑施工提供參攷和藉鑒。
