【摘要】 本文研究用改变探头加力体原长的加力方案来改变对井壁施加的面应力，以测定改变加力后的面应变固体潮，用测出的面应力和面应变固体潮的数值来求定测点水平地层的绝对面应力。更多还原

【Abstract】 This paper focuses on the measurement of absolute crustal plane stress.By varying the former length of the exerting force body of probe to change the plane pressure on well walls, the plane strain tide caused by exerting force can be measured. From the values of the strain tide and exerted stress the absolute plane stress in horizontal layer where the strainmeter is installed is obtained.更多还原
