本文简单介绍了长沙矿冶所近年来,在应用单钻孔全应力解除法,进行岩体应力测量的研究中,针对均质各向同性、及横向各向同性岩体,在孔底应变法及孔壁应变法方面所取得的一些进展。着重介绍了钻孔平底面三维应变传感器,中空包容式三轴应变计;还概述了用岩石钻孔三轴应变计进行各向异性岩体应力量测的特点、以及岩石钻孔三轴应变计的现状。
This article briefly introduces the Changsha Institute of Mining and Metallurgy in recent years, in the application of single hole full stress relief method for rock mass stress measurement research, for homogeneous isotropic and transversely isotropic rock masses, at the bottom of the strain method Some progress has been made in the pore wall strain method. The three-dimensional strain gauge and hollow-enclosed three-axis strain gauges for drilling flat surfaces are highlighted. The characteristics of anisotropic rock mass stress measurement using rock drilled triaxial strain gauges and the three-axis strain gauges for rock drilling are also outlined. The status quo.
