摘要

岩石力学试验是岩石力学的基础，是研究岩石力学与工程的重要手段之一，但岩石力学试验的结果往往要受到很多因素的影响，试验结果的离散是普遍存在的，有时可能会得到完全相反的结论。以超声波传播速度、回弹值与岩石强度之间相互关系为基础，综合两种方法的优点，把超声-回弹综合法应用到岩石试样选择中，在正式试验之前，挑出那些可能会使试验结果很离散的试样，可以提高室内试验的测试准确程度。实践表明，这种综合选样方法具有较好的适用性，对有缺陷的试样有较好的识辨能力，而且方便、快速、对试样没有损伤，同时，超声-回弹综合法可以较好地预测岩石的抗压强度。因此，这种综合方法在岩石试样选择和强度预测中值得借鉴。

Abstract

Rock mechanics is based on rock mechanics test

which is one of the most important methods in studying rock mechanics and engineering. But the experimental results of rock mechanics test are always influenced by many factors and the discrete experimental results are ubiquitous. Those bring some inaccurate or even reverse results. Based on the relationship among ultrasonic velocity

rebound value and strength of rock

the ultrasonic-rebound comprehensive method was applied to the rock sample selection which has the advantages of two methods. In order to get the accurate results

the rock specimens which may cause discrete results can be selected out first before the laboratory test. Practice shows that such a comprehensive sampling method has good applicability. It is quite convenient to distinguish the rock specimens with interior defects and has no injury. At the same time

the ultrasonic-rebound method is quite useful to predict the compressive strength. So the application of this method in sampling of rock mechanics test and strength prediction is worth using for reference.
