摘要: 本文对本所研制的BEM-1-D76型钻孔弹模仪的基本原理和各项技术指标、测试方法及现场使用情况作了介绍,并且与国外同类仪器进行了比较,从而表明该仪器是现场测定岩体变形特性的有效新设备。

Abstract: In order to measure elastic modulus of rock in a borehole, Type BEM-1-D76 Jack was developed by our institute. In this paper, working principle, targets and measuring method of this jack are introduced. It's practical applications in a region with high stress are given. In addition, the jack are compared with other similar jacks in abroad. It is shown that Type BEM-1-D76 Jack is a new effective instrument for measuring deformation behavior of rock mass.
