| 摘 要： | 利用人工力源进行中等尺度地壳岩体中的应力场实验研究的首次实验,于1982年10月至11月在唐山古冶进行。 一、实验原理、场地和设备 此次实验以水压致裂法应力测量中的注水压力作为人工力源,在水压致裂孔（简称实验孔）的附近布设装有地应力传感器的观测孔,用地应力测量系统进行现场实测。 这类实验在国内外未见报道。它不仅能够通过实验检验地应力相对测量方法的效

| Abstract: | In this paper, the studies of a stress field in medium-sized crustal rock are reported. During the tests the porehole hydraulic press was used as an artificial force source and the borehole stressometer was the measuring tool. The depth of measurement reached to more than 100 meters. The working area extended horizontally in 20 meters.It has been found that the range of additional stress field made by the artificial force soure is rather large. The change of the additional stress field has close relation to the dynamic variation of water. |
