摘　　要：根据海塘塘前的波浪条件和台灾后海塘损坏程度,迎潮面的抗浪结构采用砼贴面护面板、埋石砼重力墙和异形块体等,塘顶为砼护面。当海塘越浪量在0.05m3 (m·s)以下时,背坡面采用干砌块石,大于此越浪量的海塘,背水面采用浆砌或灌砌保护。以上护面结构的稳定性经水槽模型验证及台灾的考验。Most of seawalls are built on soft earth foundation in Zhejiang Province, and the elevation of crest is determined according to wave overtopping discharge. In the light of the wave condition in front of seawalls and the damage of seawalls after typhoon disasters, the structure of the seaward cover layer adopts concreteface plate , vertical concrete wall where rock block is embedded, and armour unit, etc. The crown is covered with concrete. The back cover layer adopts dry stone for the seawalls whose wave overtopping discharge is less than 0.05 m3/m·s; motar stone or solid cover is used for the seawalls whose overtopping dischargeis is lager than the value. The stability of most of cover layers are checked by hydraulic model tests or typhoons.
