The six sea walls constructed in xiamen seacoast from 1953 to 1979 not only changed original nature environment , but also produced many application quaternary problems : tide - absorbing capacity reducing , and the bay silt up increasing ; the coast erode going into worse , and part of coasts collapsing and falling back ; intertidal zone mangrove disappearing , and ecosystem environment being destroyed ; sand beach in seashore running off severely , quantity of sea water falling , and marine products being reduced sharply 摘要1953 - 1979年廈門沿海修筑的6條海堤不僅改變了原有的良好自然環境,而且產生了諸多應用第四紀問題:納潮量減少,港灣淤積加重;海岸侵蝕作用加劇,部分海岸崩塌后退;潮間帶紅樹林消失,生態環境遭到破壞;海濱沙灘流失嚴重,海水質量下降,水產養殖銳減。

Oceanographic information is indispensable in many activities including astronomical tides for maritime operations , storm surge levels to warn of possible sea flooding and for reclamation projects , and wave heights for shore protection , sea wall design and offshore operations 海洋物理的資料對很多活動都是不可缺少。例如海上作業要參考潮汐資料和填海工程要考慮風暴潮可能導致的水浸威脅。此外,海岸防護工作防波堤設計和離岸工程都要應用到海浪高度資料。

Geosynthetics have been used to improve bearing capacity of poor foundation in different practical engineerings , such as foundation of embankment , sea wall , oil tank and building 實踐中,加筋地基主要用于堤的軟基加筋、油罐和氣罐及條形基礎的地基加筋。

According to the requirement of sea wall and forshore management , a sea wall and foreshore information management system is developed in the stand - alone environment 根據海塘灘涂管理工作的實際要求,本文首先在單機環境中開發了海塘灘涂信息管理系統。

Because of the fact that they are largely surrounded by a sea wall , they are particularly vulnerable to pollution from vessels using them and from the shore 避風塘三面被海堤包圍,潮汐漲退沖刷能力低,特別容易受岸邊和灣內船只的污染物影響。

The sea wall sustained the shock of waves 海堤經得起海浪的沖擊。

The waves made a breach in the sea wall 海浪將防波堤沖開一個缺口。

The huge waves made a breach in the sea wall 大浪在堤上沖出一個缺口

The huge waves made a breach in the sea wall 巨浪把海防墻撞了一個裂口。

Sudden drawdown also occurs at low tide behind any sea wall which is wetted at high tide . 在高潮時浸濕的任何海堤的后面,當低潮時也會出現急遽的水面降落現象。
