| 摘 要： | 自1998年8月起,新疆地区开展土层钻孔应力测量,先后建成7个台。期间在新疆及邻区,多次发生中、强震。在部分地震前,应力仪记录到了异常,其异常类型大致有3种:(1)年变畸变型,主要表现为打破年变规律的畸变,异常时间在3个月以上;(2)阶变型异常,以快速跃变为特点,一般幅度较大;(3)波动型异常,以张压交替变化为显著特点。随着新疆土层应力测量资料的不断积累和震例的逐步增多,依据其异常类型特征有可能对地震三要素的预测有所帮助。 |

| Abstract: | Since August,1998,Xinjiang area began the measure of soil layer bore stress.It was successively completed 7 stations.During the period,there occurred many mid-strong earthquakes in Xinjiang and its adjacent area.Before part earthquakes,the stress apparatus recorded some abnormity.The abnormity type had 3 kinds approximately:(1) The distortion type of annual variation.Its main performance is to break the rule of annual variation.Its abnormal time is more than 3 months;(2) The staging change type is to take the fast jump as a characteristic.The range of change is not usually big;(3) The undulation abnormity type is to take open and pressure in turn as the remarkable characteristic.With the unceasing accumulation of measure data about the soil layer stress and the gradual increase of the events in the Xinjiang soil layer stress,according to the abnormity type characteristic,it is the possibility to have the help for the prediction of earthquake three essential factors. |
| Keywords: | Soil layer bore stress measure Abnormity type The distortion of annual variation Stress staging change Earthquake prediction |
