摘　　要：锦州滨海地区地势低平,地貌类型单一,基岩埋深较浅,地下水富水性较差,工程地质分区简单,地质灾害不发育,比较适合工程建设活动。为支撑锦州滨海新区规划布局及规范工程建设活动,需要充分掌握辽西滨海地区岩土体工程地质特征,进而圈定工程建设活动适宜性范围。本研究通过对岩土体工程地质特征进行分析,定性评价了区域地壳稳定性,并结合滨海丘陵地区主要地质环境问题,首次将海咸水入侵、软土厚度等指标列入辽西滨海地区工程建设适宜性评价指标体系中,采用层次分析法,定量评价了研究区工程建设适宜性。研究结果显示,锦州滨海地区可划分岩体3大类,土体2大类;区内无全新活动断裂,地壳稳定性较好,地面稳定性较好,场地稳定性为稳定—基本稳定场地;工程建设适宜性大部分属于适宜等级,占总面积的87.44%;仅有12.56%的面积属于较适宜级。较适宜区在工程建设过程中主要防止地下水位埋深过浅导致建筑物腐蚀以及地下建设空间渗水等情况。The coastal area of Jinzhou is suitable for engineering construction activities because of its simple topography and geomorphologic type,shallow burial depth of bedrock,poor groundwater richness,simple engineering geological zoning and lack of geological disasters.In order to support the planning and layout of the coastal area of western Liaoning Province and the specification of engineering construction activities,the engineering geological characteristics of geotechnical bodies in the area are studied,and the suitable range of engineering construction activities is defined.Based on the analysis of geotechnical engineering geological characteristics,regional crustal stability has been qualitatively evaluated.Considering the main geological environment problems in coastal hilly areas,the index of saltwater intrusion and soft soil thickness are included in the evaluation index system of engineering construction suitability in the coastal area of western Liaoning Province for the first time.The research results show that,the Jinzhou coastal area is divided into three categories of rock mass and two categories of soil mass;There is no new active fault in the study area,the crust stability is good,the ground stability is good,and the site stability is stable to basically stable;The suitability of engineering construction mostly belongs to the suitability level,accounting for 87.44%of the total area;Only 12.56%of the area belongs to the more suitable level.The more suitable area mainly prevents corrosion of buildings caused by shallow groundwater levels and water seepage in underground construction spaces during the engineering construction process.
