实孔法深层三向相对应力测量

Measurement of relative crustal stress at great depth by solid-hole method

深地层注浆固化核废料场地的地应力变化趋势是评估其安全性的重要参考之一。作者介绍了为某深地层注浆固化处置中放核废液工程而进行的实孔法深层三向相对应力测量的有关情况。分析了封井介质与周围岩体介质性质差异对应力测量数据的影响。从分析的结果看,要得到比较真实的应力信息,考虑介质性质差异对测量数据的修正是非常必要的。

The measurement of three-dimension relative crustal stress at great depth in the medium-level radioactivity waste disposal field is briefly introduced. The effect of properties difference betweeen the sealing-hole medium and the rock on crustal stress measurement data is analyzed. It is necessary to consider modification of measurement data due to the property difference of the media.
