【摘要】 地应力测量技术的研究已有几十年的历史， 但是对于地下深部地应力非钻孔式测量探测技术的发展， 则一直进展很慢． 本文依据天然电磁波场源， 利用光弹实验模型原理， 研制了 Ｄ Ｙ Ｌ 型地应力探测仪， 并在淮南地区地应力状态普查过程中， 取得了明显的应用效果更多还原

【Abstract】 Although geothress survey technology has be studying about tens years,the developing of detecting depth geostess technology without drill hole is constantly slowly advanceing. DYL type geostress detecting instrument is made relied on principle of photoelastic test model,which used natural electromagnetic wave field. It was used in census of geostress in Huainan region and its applied result is obvious.更多还原
