摘要

摘要: 本文通过土工实验分析，发现河北南堡-曹妃甸海域沉积物主要由淤泥、粉砂、黏土和粉土组成，约占总沉积物的85%，另含有少量的淤泥质黏土、粉质黏土、细砂和中砂。综合归纳南堡-曹妃甸海域的工程地质条件，根据影响研究区工程地质条件差异性最突出的因素即海底地形地貌、潜在地质灾害分布，结合海底土质类型及其物理力学性质等条件，将研究区划为4个工程地质区，分别为近岸水下岸坡混合土工程地质区（Ⅰ）、侵蚀平原、洼地砂质土工程地质区（Ⅱ）、侵蚀洼地混合土工程地质区（Ⅲ）、陆架堆积平原细粒土工程地质区（Ⅳ）。通过海洋环境因素、灾害地质条件、地震活动性、海底土体稳定性等方面对各工程地质区进行海底稳定性评价，4个工程地质区的稳定性分别为Ⅰ区：不稳定区；Ⅱ区：较稳定区；Ⅲ区：较不稳定区；Ⅳ区：稳定区。研究成果对该地区的海底工程建设和防灾减灾具有重要的指导意义。

Abstract: In this paper, through the analysis of geotechnical test, sediment of the sea around Nanpu-Caofeidian is mainly composed of mud, silty sand, clay, silty soil, which account for 85% of the total number of analyzed samples. Muddy clay, silty clay, fine sand and medium sand are relatively less. According to the most prominent factor which influence the geotechnical conditions of Nanpu-Caofeidian area: submarine landform unit, potential geological hazards, combined with submarine soil type and its physical and mechanical properties, the research area can divide into four engineering geological zone, they are subaqueous slope mixed engineering geological zone(Ⅰ), erosion plain and depression sandy soil engineering geological zone(Ⅱ), erosion depression mixed engineering geological zone(Ⅲ), shelf accumulation plain fine grained soil engineering geological zone (Ⅳ) respectively. Through comprehensive analysis of the factors which influence the geotechnical conditions of sea floor by marine environment factors, seismic activity, disaster geology and soil stability, the seabed stability of the four engineering geological zones are unstable area(Ⅰ), relatively stable area (Ⅱ), relatively unstable area(Ⅲ), stable area (Ⅳ). The research results have important guiding significance for the construction and disaster prevention and reduction of the sea floor in this area.
