岩石扩容现象与超声横波特征参数相互关系研究评述
|
摘要
介绍了岩石扩容现象与超声横波特征参数相互关系相关专业领域研究的现状及其应用。在用横波速度最大值 ( vsmax)来分析岩石微裂纹初始扩展时的应力值 (应力门槛值 )新方法的基础上 ,建议利用主动的人工横波震源、应力门槛值、vsmax后的横波速度值与岩石裂纹加速发展的同步减小特性 ,更深入地进行地震破裂丛集及前兆特征的研究 ,有可能建立地震和地质灾害性预报的新方法。并提出利用传统方法研究岩石扩容机理、应力门槛值、泊松比等的同时 ,进行岩石扩容现象、声发射和超声波横波等物性参数相互关系研究的新思路
This paper introduces some new developments and their tectonic significance in the study of the ralationship between the dilatancy of rocks and the characteristic parameters of shear wave under formation conditions, in rock mechanics and geophysics. Baced on a new method to analyse the stress value of stress induced microcracks by the peak value of the S wave velocity, the authors suggest, by using this man made S wave focus of an earthquake and the special property, that the S wave velocity peak value illustrates the production of new microcracks and the velocity begins to decrease with the expansion of microcracks rupture in the test sample. To make a through rsearch of earthquake crack nucleation and its precursor will be lead to take shape the new calamity forecasting method of the seismic and geology. It also advances a new thinking that finds the Poisson's ratio corresponding to stress value is cut down.
