摘要
本文讨论了北京地区的地震活动。并应用模糊数学方法、根据区域稳定的影响因素特点将其模糊信息化,建立了模糊识别模型,并根据北京地区的地震地质等条件对北京地区区域稳定性作了模糊综合评定。
The seismic activity and geological structures in Beijing Municipality and its adjacent regions are discussed in this paper. By using fuzzy mathematics, the fuzzy comprehensive evzluation of regional crustal stability in the Beijing area has been made through transforming the factors controlling regional crustal stability into fuzzy information, and a model of fuzzy comprehensive evaluation is established.The final conclusion shows that the Fengheying-Xianghe-Tongxian-Sunhe-East Changping area is unstable and relatively unstable. The a tea west of Fangshan-Mentougou and the northeast of the Miyun-Jixian area and the mountainous area in the north are relatively stable and stable. Other areas are less stable. The eastern and north-eastern parts of Beijing Municipality are relative unstable. The stability of Beijing City proper is situated between relatively unstable areas and less stable areas. Its stability index is not high, corresponding to a seismic intensity of 7°—8° by means of sighle factor evaluation.
