本文根据浙江省海堤历次破坏的情况,对海堤破坏的类型、原因进行了较为系统的分析。总结了6个方面的原因,即:(1)堤顶高程不足,潮浪漫顶或越浪破坏;(2)干砌块石护面砌体质量差,易变形倒塌;(3)地基软弱容易发生沉滑破坏;(4)土石体间未设置过渡层或过渡层不合格;(5)渗漏破坏;(6)其他方面的原因,如选用堤型或堤线布置不合理,潮流沟的危害,维护管理差等。针对破坏原因还提出了相应的防范措施,即:必须进一步提高对海堤工程重要性的认识;努力提高海堤防御标准;建设一道较为巩固的防台御潮的基本防线;重视生物措施护堤,强化管理工作等。
In this paper, according to the previous cases of seawall damage in Zhejiang Province, the types and causes of the seawall damage are systematically analyzed. The reasons of the six aspects are summarized as follows: (1) the embankment elevation is not enough, the tide is romance top or the overwhelming damage; (2) the quality of the dry masonry masonry masonry body is poor and is easy to deform and collapse; (3) the foundation is weak and easy (4) The transition layer or transition layer is not set up between soil and stone body; (5) The leakage is damaged; (6) For other reasons, such as the choice of embankment or embankment arrangement is not reasonable, tidal current ditch Hazard, poor maintenance and management. In view of the causes of the damage, corresponding preventive measures are also put forward, that is, it is necessary to further raise awareness of the importance of the seawall project, to strive to improve the standards of the seawall defense, to build a more consolidated basic defense line against typhoon prevention, , Strengthen management and so on.
