A large polyaxial loading system is being procured, which will be employed to apply triaxial compression to large (l2 x l2 x l2 in) specimens of rock. The equipment to be procured includes flatjacks, hydraulic assemblies, a hydraulic pump, and a data acquisition system. The equipment will initially be utilized to investigate: the spall failures induced in deep bore holes by field stresses and thermal stresses; the shear conductivity for dilatant rock joints; acoustic emission monitoring of fluid injection into various types of rock; failure theories of coal which will include three dimensional stress effects; and inelastic effects and residual strain in stress measurements of rock masses.

正在采购一个大型多轴加载系统， 用于对大型（l2 x l2 x l2 in） 岩石标本 拟采购的设备包括平板千斤顶， 液压组件、液压泵和数据采集系统。 这些设备最初将用于研究： 应力和热应力引起的深钻孔破坏 应力;裂隙岩体的剪切传导系数;声波 对注入各种岩石的流体进行排放监测; 煤的破坏理论，包括三维应力 应力中的非弹性效应和残余应变 测量岩石质量。
