岩石试件受载破裂过程地球物理参数测试研究进展和展望

    PROGRESS AND PROSPECTS OF TESTING GEOPHYSICAL PARAMETERS DURING LOADED RUPTURE OF ROCK SPECIMENS

    • 摘要: 试件尺度的岩石受载破裂过程中,其本身结构发生变形、破坏的同时,包含了地球物理属性参数信息的变化,如应变量、电阻率、波速等。通过对受载中的岩石试件进行地球物理参数测试,可定性或定量地感知其内部结构、强度等特征变化,有助于了解岩石试件破裂机理,进而解决一系列岩体工程测试问题。基于Web of Science论文检索系统搜索出岩石试件加载测试的文献资料,利用CiteSpace软件对岩石试件加载测试现状进行分析,并详细阐述了几种常用测试方法的原理及研究进展。结合煤系地层深部采场领域研究现状,分析、总结岩石试件受载测试研究过程中存在的不足,并对地球物理参数采集、装置研发与微-宏观测试融合等方面提出展望。

       

      Abstract: The specimen-scale rock under load rupture process, while its own structure deformation and damage, contains the change of geophysical property parameter information, such as strain, resistivity, wave velocity, etc. By testing the geophysical parameters of the rock specimen under load, the change of its internal structure, strength and other characteristics can be perceived qualitatively or quantitatively, which is helpful to understand the fracture mechanism of the rock specimen and solve a series of rock engineering testing problems. Based on the Web of Science paper retrieval system, we searched the literature on rock specimen loading tests, analyzed the current status of rock specimen loading tests by using CiteSpace software, and elaborated the principles and research progress of several common testing methods. In light of the current research situation in the field of deep mining of coal strata, the shortcomings in the research process of rock specimen loading tests are analyzed and summarized, and the prospects of geophysical parameter acquisition, device development, and micro-macro test integration are proposed.
