测量地应力的新方法

论述了用赤平投影学方法分析确定地应力的主方向，用Kaiser效应测量地应力大小。将两者有机结合起来可以克服Kaiser效应测量地应力时，主应力方向难以确定的最大缺点。通过和传统现场地应力测量方法比较，表明该法具有更为简单，更为经济，准确度高等优点，便于大量测量，以寻求工程地区地应力变化规律。

The new method to measure geostress of rock mass

In this paper,the authors found out the principal direction of initial stresses with the method of geomechanics and stereography and measured the magnitude of initial stresses by acoustic emission Kaiser effect test in laboratory.The geomechanical method combined with Kaiser effect can overcome the shortcoming of Kaiser effect.Comparison with traditional methods of measuring in-situ stresses shows that the new method is more simple,economical and convenient for a large quantity of measuring and studying in-situ stresses.
