冲击凿入试验对于研究快速交变载荷作用下岩石的变化过程十分重要。这一点在通常的试验机上很难实现。岩石的力－凿深曲线与凿入时岩石的破碎特性密切相关。大量的实验研究结果表明，冲击凿入岩石的力－凿深曲线斜率比静压凿入的为大；至于二者的定量关系，各学者之间的研究结果存在较大差异。本文所介绍的冲击凿入试验系统包括打击锤（即活塞）及带球齿钎头的柱型钎杆。应力波由一对半导体应变片测定，并据此计算凿入力及凿深。在９种岩石上分别进行了冲击及静压凿入试验，并计算出相应的力－凿深特性曲线；同时还测取岩石的抗压强度、压裂拉伸强度、杨氏模量、史密特反弹硬度及肖氏硬度。试验结果表明，动载静凿入的力－凿深曲线两者间相关性很好，冲击凿入曲线斜率ｋ＿ｄ与静压凿入曲线斜率ｋ＿ｓ的关系为：ｋ＿ｄ＝１．２ｋ＿ｓ，ｋ＿ｄ与ｋ＿ｓ二者并非总是相差２０％。
Impact chipping test is very important for studying the process of rock change under rapid alternating load. This is difficult to achieve with conventional test machines. The rock’s force-depth curve is closely related to the crushing characteristics of the rock during cutting. The results of a large number of experiments show that the slope of the force-sinking curve of impacted rock is larger than that of static pressure. As for the quantitative relationship between the two, there are great differences among the scholars. The impact and penetration test system introduced in this paper includes a hammer (ie, piston) and a drill rod with a ball bit. The stress wave is measured by a pair of semiconductor strain gages and the chisel penetration depth and depth are calculated accordingly. Impact and hydrostatic jacking tests were carried out on nine kinds of rock respectively, and the corresponding force-depth characteristic curves were calculated. Meanwhile, the compressive strength, tensile strength, Young’s modulus, history Mite rebound hardness and Shore hardness. The test results show that the correlation between the force-chiseling curve of dynamic loading and static chiseling is very good. The relationship between the slope of impact chipping curve k_d and the slope of hydrostatic caving curve k_s is: k_d = 1.2k_s, k_d and k_s The two are not always different by 20%.
