摘　　要：钱塘江沿线古海塘连绵几十千米,有海上长城之美誉,因海塘堤脚常年遭受涌潮掏刷,亟需采取加固措施。钱塘江沿线海塘强涌潮冲击大,采用传统的围堰施工工艺难度高,易被冲毁。同时,古海塘属于国家级文物,保护要求高。为避免古海塘受压载破坏,首次探索采用钢栈桥技术在江中搭设施工作业平台,经实践证明,该施工工艺技术可行,实施效果较好,不仅保护了古海塘的结构安全,而且施工不受潮水、台汛期的制约,同时后期钢栈桥拆除便捷,对江道环境影响小,满足施工要求,对后续开展的海塘工程建设具有重要参考价值。The ancient seawall along the Qiantang River stretches for tens of kilometers,and is reputed as the Great Wall on the sea.Because the seawall toe is scoured by tidal bore all year round,it is urgent to take reinforcement measures.The strong tidal bore of the seawall along the Qiantang River has a great impact,so it is difficult to adopt the traditional cofferdam construction technology and is easy to be washed out.At the same time,the ancient seawall is a national cultural relic,which requires high protection.In order to avoid the damage of the ancient seawall under pressure load,the steel trestle technology was first explored to set up a construction platform in the river.The practice has proved that the construction technology is feasible and the implementation effect is good.It not only protects the structural safety of the ancient seawall,but also the construction is not restricted by the tide and the flood season.At the same time,the steel trestle removal in the later stage is convenient,has little impact on the river environment,and meets the construction requirements,it has important reference value for the subsequent construction of seawall engineering.
