岳城水库区域断裂活动性特征分析

Analysis of Yuecheng Reservoir Regional Fracture Activity and Seismic Activity Characteristics

断裂的活动可能对水库大坝造成严重影响,研究水库区域内断裂的活动性对评价水库大坝安全有重要意义。本文对岳城水库区域内断裂的活动性进行了分析,并根据历史地震目录和邯郸地震台网1970～2005年的现今地震目录,初步研究了水库主坝区和周边研究区的地震活动特征与活动断裂的关系,对科学判定断裂对大坝的影响进行了探讨。

Fracture activities are influential to reservoir dams. It is of great significance to research the influence of fracture activities on dams. Through detailed analysis and research of the regional fracture activities of the Yuecheng reservoir, and on the basis of the earthquake catalogue of Handan Digital Seismic Network from 1970 to 2005, the relationship between characteristics of seismic activity in the reservoir dam areas and nearby areas and fracture activity is preliminarily analyzed, and the influence of fracture on the dam is explored.
