在回弹试验中，测量结果受直接地表和次地表特性的影响。标准的施密特锤子释放的能量如此之大，以至于影响层可以达到几厘米厚。两种低冲击能量的回弹装置，球回弹和Equotip仪器，已经在花岗岩，石灰岩和砂岩样品上进行了评估。讨论了试验结果与其他岩石性质之间的相关性。考察了深度对这些试验的影响以及计算不连续墙强度的影响。
In rebound tests, measurements are influenced by characteristics of the immediate surface and the subsurface. The standard Schmidt hammer releases so much energy that the layer of influence can be up to centimetres thick. Two rebound devices of much lower impact energy, ball rebound and Equotip instruments, have been evaluated on granite, limestone, and sandstone samples. Correlations between results of the tests and with other rock properties are discussed. Influence of depth in these tests and calculating discontinuity wall strength are examined.
