摘要
给出根据单孔变形的实测结果计算三维地应力状态的最小二乘法，设计并通过实验系统研究了能够测量三维地应力的压磁全应力计，最后通过野外实测检验说明该应力计测量结果是可靠的。
A least square solution, which is to determine the state of the three dimensional stress in the crust with the date measured by the single borehole deformation method , has been worked out.Then,a three dimensional piezomagnetic stressometer has been developed and the experimental researches have been systematically made. Finally, by field testing, it has been shown that the measurement results of this stressometer to determine the state of three dimensional stress in the crust are reliable.
