德令哈地震台分量钻孔应变干扰分析
Analysis of interference characteristics of borehole strain at Delingha Seismic Station
摘要
Abstract
In this article we have analyzed the correlation between the data of the borehole water level and Heishishan reservoir water level and borehole strain observation data at Delingha Seismic Station.Through the concentrated load model we have calculated the interference values of reservoir loads on borehole strain observation,which are compared with the observed value.The results show that reservoir impounding has caused serious interference to borehole strain observation.Reservoir loads and permeation have less effect on the borehole strain observation.Reservoir water level changes lead to changes in the hydraulic pressure of the surrounding rock mass,which may be the main factor influencing the borehole strain observation.关键词
