摘要:
以渤海海域海底地质灾害为研究目标，采用层次分析法（Analytic Hierarchy Process, AHP），按照海洋水动力条件、工程地质环境、灾害地质条件、人类工程活动4个类别，遴选了8个评价因子，详细论述了各地质灾害评价因子的分布特征，通过定性分析和定量计算相结合，开展了渤海海域海底地质灾害评价及危险性区划。将渤海海域海底综合划分为地质灾害危险性高危险性、较高危险性、较低危险性和低危险性4个区域。研究成果可为渤海海域的工程建设和防灾减灾提供科学依据。
Abstract:This paper established the system of assessment in dex for regionalization of geological hazards in Bohai Sea with four aspects of hydrodynamic condition, engineering geological environment, disaster geological conditions and human engineering activities based on analytic hierarchy process, eight evaluation factors selected and the distribution characteristics of each geological hazard evaluation factor which were discussed in detail. The integrated geological disaster evaluation and regionalization were carried out combined with qualitative analysis and quantitative calculation. The risk level of submarine geological hazards in Bohai Sea are divided into four types: high, medium-high, medium-low and low.The study results can provide scientific basis for engineering construction and hazard prevention in Bohai Sea area.
