摘　　要：对气压非周期性波动、高频脉动干扰,水位升降变化引起的体应变观测分钟值数据曲线畸变现象进行了对比分析。结果表明,钻孔区域的岩体应力-应变变化幅度与气压变化幅度大小有关,地下水位的升降与应力-应变状态有一定关系,即水库泄洪量在16.0 m3/s左右时,体应变呈压性速率明显增强的阶变形态,泄洪结束后河水流量恢复正常的过程中,造成体应变明显张性畸变。According to comparison analysis on data distortion of body strain caused by nonpenoolc vibration of pressure .high frequency interference and level variation of water level, the results show： The change of rock stress and strain is related to pressure and water level in borehole; when flood discharge is about 16.0 m3/s, the body strain stressing obviously while turning to tensional interference after water discharge is over.
