摘　　要：描述了安徽省地震局"十一五"期间安装的5套钻孔体应变仪的地质构造特点与钻孔岩芯物理特性,介绍了TJ-Ⅱ体应变仪的运行情况。通过对两次强震活动的同震效应分析,初步探讨了地理、地质构造条件不同的情况下,各观测井对记录应力活动能力强弱的反映。In this paper, we describe the five borehole bulk strains＇ geological characteristics and core physical properties which are built by Earthquake Administration of Anhui Province in the eleventh Five-year （2006--2010） Plan, and introduce the operation situation. The results of analysis show that the each observation well is influenced by different geographical and geological conditions after activities of the two strong earthquakes. It is helpful for enhancing ours ability to utilize the observed data, and promoting the earthquake prediction. It also has an important significance for instrument installation.
