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
The first experiment on the experimental study of stress field in medium-scale crustal rock mass using artificial force source was carried out in Tangshan Guye from October to November, 1982. First, the experimental principle, the venue and equipment In this experiment, water pressure fracturing method in the pressure measurement of water pressure as an artificial source of hydraulic fractures in the hole (near the experimental hole) is equipped with ground stress sensor observation hole, Site stress measurement system for field measurements. Such experiments have not been reported at home and abroad. It can not only test the effectiveness of the relative measurement method of ground stress by experiment
