蚌埠钻孔应变受抽水干扰的分析

摘要

分析了蚌埠地震台体应变受抽水的干扰情况,并给予了较合理的解释.通过对蚌埠台体应变数据的趋势变化分析,认为抽水干扰不是影响该台体应变观测数据趋势变化的主要因素；又通过区域不同台站体应变数据的对比分析,得到区域应力场是影响应变观测曲线变化的主要因素的论断.为使用该台体应变数据提供了参考,同时也为体应变的选址提供了参考实例.%The pumping disturbance on the bore-hole body strain for Bengbu seismic station in Anhui is analyzed, and logical explain is given. Through analyzing the trend change of Bengbu body strain observation data, it is considered that the pumping disturbance not main factor for the tread change. Through analyzing the body strain observation datas from several stations in this region, it is found that the change of regional stress field is main factor for the tread change of Bengbu body strain. The result gives a reference to using Bengbu body strain observation data, and offer a example to select site for body strain observation.
