| 摘 要： | 随着人类对深部矿产资源和能源材料的需求量持续增长,深部开采问题必将成为工程界所面临的重大问题,而地应力参数的准确确定是有效解决该重大问题的基础工作之一。文章总结了目前在能源和资源开采中使用较为广泛的26种地应力测试方法,并对这些方法的基本力学原理、发展史作了简要介绍。这26种方法按照数据源途径可以分为5大类,分别为基于岩芯的方法、基于钻孔的方法、地质学方法、地球物理学方法以及基于地下空间的方法。这些方法依据满足工作需要的角度又可以分为主动法和现象分析法,对于社会基础设施建设、深部能源和资源开发,主动法的适用范围更广。不同的方法所反应的应力信息是不同的,相对而言建立在大体量岩体上的方法对于分析区域应力场更为可靠。最后文章对未来的应力测量与估算的发展远景进行了展望。

| Abstract: | With the demand for mineral and energy resources at great depth increasing rapidly, scientists and engineers are faced with difficult exploitation problems from the deep, to determine or define in situ stresses accurately is one of the most fundamental tasks to solve the above problems. This paper summarizes 26 stress estimate and measurement methods widely used in energy and mining industry, and briefly reviews the mechanical principles and development history of these methods. From the viewpoint of where these data come from, these 26 methods can be classified into five categories, core based method, borehole based method, geological method, geophysical method and underground opening based method. From the point of meeting the needs of human beings, these methods also can be divided into two groups, active methods, and phenomenon based methods. For social infrastructures, deep exploitation of energy and mineral resources, the active methods are more applicable. The different methods reflect stress information at different volume scales, but the methods based on the large scale rock mass may offer more stable and reliable stress data for the analysis of a regional stress field. Finally, the author discusses some future prospects of the in situ stress measurement techniques. |
