| 摘 要： | 对山东省钻孔体应变仪数字化观测资料的干扰及突跳异常进行了分析、讨论，认为：(1)山东省四个台站的钻孔体应变观测资料不同程度地受降雨、地下水位、气压、温度的影响，其中，烟台台体应变观测受到的干扰最多，影响最显，主要与其钻孔的地质条件有关。(2)长清台体应变观测资料中出现的几次突跳异常是由井孔内破碎带处掉下的岩块引起的变化。 |

| Abstract: | This paper discussed and analyzed the disturbance mechanism and jumping abnormity of digital observations of borehole body strain meters in Shandong Province.The results show that the observations of four body strain meters were differently influenced by rainfall,underground water,air pressure and temperature.Among which,the disturbance of Yantai body strain observation is the biggest which is related with the geological condition of Yantai bore hole.The several jumping abnormities of observations of Changqing body strain meter were induced by rock blocks that dropped from shatter belt in the bore hole. |
| Keywords: | strain of bore-hole body observation data analysis of abnormity Shandong |
