摘要/Abstract

摘要： 为解决现有的地质灾害危险性评估技术方法和规范不完善,且不能满足海上风电场工程项目建设要求的问题。以东南沿海首个海上风电场地质灾害危险性评估为工程实例,首先,分析场区特殊的海洋地质环境条件和项目的特点;然后,开展地质灾害危险性现状评估、预测评估和综合性评估;最后,提出具体的预防治理措施。结果表明:工程场地地质灾害危险性等级为小到中等,综合评估分级属适宜建设海上风电场,但应对场区内存在的海床冲淤、软弱土、液化土及孤石等问题采取可靠的措施。

Abstract: In order to address the imperfection of existing technical methods and specifications for geological disaster risk assessment and their insufficiency in meeting requirements for construction of offshore wind farm projects, relevant studies were conducted with risk assessment of the first offshore wind farm in the southeast coast of China as an engineering example. Firstly, special marine geological environment conditions and characteristics of the project were analyzed. Then, geological hazard assessment, prediction assessment and comprehensive assessment were carried out. Finally, specific prevention and control measures were proposed. The results show that the geological hazard grade of the engineering site is small to medium, and comprehensive assessment grade is suitable for construction of offshore wind farms. However, reliable measures should be taken for problems of seabed erosion and deposition, soft soil, liquefied soil and solitary rock in the site.

Key words: offshore wind farm, geological disaster, risk assessment, prevention measures, liquefied sand
