摘要
新城金矿地应力场测量采用应力解除法和实现完全温度补偿的空心包体应变测量技术。为了提高测量结果的可靠性和精度，在现场测量和结果计算、分析过程中，采用了完全温度补偿技术，自动应变测量和记录系统，用双迭代程序求测点岩石弹性模量、泊松比和测点ｋ系数、地应力值等一系列新理论、新技术．现场实测获得矿区４个水平、 １７个测点的三维应力状态，并根据实测结果对矿区地应力场的分布规律进行了详细分析，建立了矿区地应力场分布模型。
This paper introduces techniques and results of in situ stress measurement at Xincheng Gold Mine. For increasing reliability and accuracy of the measurement, a series of new techniques were used in the measurement. Through the measurement, 3-D in situ stress state at 17 points distributed on 4 levels was obtained. Based on the measured results, distribution regularity of in situ stress state and its relation to geological tectonics are analyzed.
