随着科学技术的发展,岩石力学这门新兴的科学在采矿、水电、铁道等工程中占有日益重要的地位。岩体应力测量是了解岩休受力状况的有效方法。目前,用孔壁变形法测试岩体应力,在国内已被越来越多的单位所采用。该方法具有工程帚小,只需打一个孔就可确定一点空问应力状态蛀七点。这样就可m节省大量的人力、物力、财力,并n能节省时间。但用 With the development of science and technology, the emerging science of rock mechanics occupies an increasingly important position in the mining, hydropower and railway engineering. Rock mass stress measurement is an effective method to understand the rock stress state. At present, the test of rock mass stress by pore wall deformation method has been adopted by more and more units in China. The method has the engineering broom small, just hit a hole to determine a little space stress state moth seven points. This will save a lot of manpower, material and financial resources, and n can save time. But use
