摘要
本文以地处南流江冲积成因为主的古滨海平原的地貌、松散沉积物及其工程地质特性、场地土、场地类别、场地周期等环境特点为基础，对北海市进行了地震设防区划。将北海市划分为残丘区、台地区和阶地海滩区三个地质地貌单元和相应的三个地震设防分区，每个地震设防区给出相应的地震影响系数。文中还对场地地震地质灾害进行了评估和预测。
The seismo geotechnical environmental characteristics of Beihai City area are discussed from data of geomorphic features, unconsolidated deposits, site soil and site types, and period of site in the paper. Three geologic geomorphic elements and three earthquake resistant zones with design ground motion parameters were delineated from seismo geotechnical environmental characteristics of the Beihai City area. The evaluation and prediction of seismo geologic hazards in Beihai City area are also given here.
