对空心包体式钻孔三向应变计的地应力测量方法进行了系统的研究，推导了资料整理的计算公式。对应变片并非直接粘贴在钻孔岩壁上而引入的修正系数Ｋｉ和各因素对它的影响以及由它的误差所导致的测量误差，进行了分析。 The method of measuring the in-situ stress of the three-way hollow bored borehole strain gauges was systematically studied, and the formula of data collation was deduced. The correction factor Ki introduced by the strain gage not directly attached to the borehole wall and the influence of various factors on it as well as the measurement error caused by its error are analyzed.
