摘　　要：本文对1700年以来的历史地震烈度资料进行了分析,并结合地震地质资料来确定设定地震(Scenario Earthquake),然后利用模拟强地面运动确定了廊坊地区的强地面运动灾害。研究结果表明,按照目前的地震活动趋势,廊坊地区出现大于或等于地震烈度8度的周期大约是600年。也就是说,在未来50年廊坊地区出现地震烈度8度的超越概率为8%。为此,本文建议廊坊地区应该考虑0.3g峰值加速度(Ⅷ度)作为基本地震工程设计参数。This paper attempts to analyze the data from 1700-year intensity observation, and to combine seismology and geology data to determine the scenario earthquake, then to simulate strong ground motion to evaluate seismic hazard in Langfang. The study results show that the period of greater than or equal to V$ intensity is about 600 years according to the current seismic activity trend. In other words, the probability of exceedance of VI~ intensity in 50 years is 8 percent in Langfang area. We suggest that it should be considered 0.3g peak ground acceleration （V$ intensity ） as the basic earthquake engineering design parameters in Langfang area.
