强涌浪海域海塘防护的技术实践

Embankment Protection Measures in Strong Sea Swell Areas

浙江沿海岛屿分布广泛,在开敞式多岛屿的海域中,波浪与多岛屿的相互作用是一个相当复杂的物理过程,地形复杂且同时受风浪和涌浪的作用,势必会影响波浪场的分布,在强涌浪海域进行工程结构保护也是工程亟需要解决的问题。以强涌浪海域的海塘工程(栲门大坝)为典型工程,利用MIKE21谱波浪(SW)模型对复杂地形的波浪场进行计算分析,对强涌浪海域提出工程防护措施。

Islands are widely distributed in Zhejiang coast The interaction between waves and multi-island is a rather complex physical process in the open multi-island waters.Complex terrain and effects by waves and swells at the same time are bound to affect distribution of wave fields.How to protect the engineering structure in the strong sea swell areas is also an urgent problem to be solved.In this paper,the authors take seawall project in strong sea swell areas(Kaomen Dam)as a typical project,MIKE21spectral wave(SW)model was used to simulate wave fields of complex terrain.Engineering protection measures for strong sea swell areas were proposed.
