二、三维高密度电法在临汾龙祠地震台水准测量巨幅形变异常判别中的研究与应用

APPLICATION OF TWO AND THREE DIMENSIONAL HIGH-DENSITY ELECTRICAL EXPLORATION ON THE HUGE DEFORMATION ANOMALY DETEMINATION OF SHORT-LINE LEVELING IN LONGCI STATIOM, LINFEN

摘要: 2010年1月7日临汾中心地震台龙祠短水准测线Bm3点出现巨幅形变,其日沉降量达10mm以上。为了查明形变点产生巨幅形变的原因,山西省地震工程勘察研究院承担了Bm3点为中心场地地震地质勘察工作,运用二维高密度电法及三维高密度电法对隐伏断裂进行勘察,并对附近的地质环境和巨幅形变产生的原因进行分析,为地震预报工作提供依据。

Abstract: The huge deformation occurred in Longci short-line leveling observation point Bm 3 on January 7, 2010 in Linfen central earthquake station, the daily subsidence amounted to more than 10 mm.In order to identify the deformation mechanism, Shanxi Province Earthquake Engineering Investigation Institute carried out the seismic geological survey around the Bm 3 point by using two and three dimensional high-density electrical exploration to detect the buried fault, and analyze the geological environment and the causes of huge deformation to provide a basis for earthquake forecast.
