摘要
使用DYL型地应力测量仪 ,利用天然场源在地面上探测地下 5km、 7km、 1 0km深部地质体所承受地应力的相对大小。通过探测的地应力值相对大小和绘制等值线图的方法研究地下应力分布状态 。
By using of DYL type measuring instrument,the relative crustal stresses on crude field fountain of geologic bodies depth of 5km,7km,10km are explored.Comparing the relative values of crustal stresses with each other,and making up the isogram,the state of relative crustal stresses is studied,after that,the position and magnitude for the seismic risk region can be gained.
