摘要
天津市滨海新区地处华北平原东北部,软土覆盖层厚,在地震作用下,产生的震害要比基岩和硬土场地严重得多。天津是地震频发区,历史上曾多次遭受6级以上地震波及,因此研究滨海新区场地类别分区具有重要现实意义。文章通过滨海新区及周边地区地震工程地质标准钻孔和工程地质等基础资料的收集整理,并辅以地震工程地质标准钻孔补充勘察,按照《场地地震工程地质条件调查》中的方法,给出了天津市滨海新区的场地类别分区结果,增进了对滨海新区地震灾害风险空间分布的认识。
Tianjin Binhai New Area is located in the northeastern part of the North China Plain.The soft soil cover is thick.Under the action of earthquakes,the seismic damage is more serious than that of bedrock and hard soil sites.Tianjin is an earthquake-prone area,which has been affected by seismic waves of more than 6 in history.Therefore,it is of great practical significance to study the site classification of Binhai New Area.In this paper,through the collection and collation of basic data such as seismic engineering geological standard boreholes and engineering geology in Binhai New Area and surrounding areas,supplemented by supplementary survey of seismic engineering geological standard boreholes,according to the method given by'site seismic engineering geological condition survey',the site classification results of Tianjin Binhai New Area are given,which improves the understanding of the spatial distribution of seismic disaster risk in Binhai New Area.
