试验机弹性储能对岩石力学性能测试的影响

EFFECT OF ELASTIC ACCUMULATION ENERGY OF TESTING MACHINE ON THE MECHANICAL MEASUREMENT OF ROCKS

  • 摘要: 在材料试验机上进行岩石力学性能测试时, 如何准确测量岩石的变形是整个测试分析的基础. 为了具体考察试验机刚度对岩石变形测量的影响程度,在两台不同的试验机上进行了岩石的单轴压缩试验,通过对加卸载过程中试验系统及岩石能量变化的分析,详细研究了试验系统弹性储能对岩石变形测量的影响,进而给出了基于试验机刚度的修正计算方法, 来确定岩石在测试过程中的变形.

     

    Abstract: It is a fundamental problem of the rock mechanicalmeasurements in material testing machine how to measure the rockdeformation exactly. Rock uniaxial compression tests were carried out in twodifferent testing machine so as to investigate the effect of machinestiffness on the deformation measurement. The energy transfer and conversionof testing system and sample during the loading and unloading processes areanalyzed in this paper. It is found that the elasticaccumulation energy of material testing machine affects the mechanicalmeasurement of rocks. Moreover a revised method is proposed which can beadopted to calculate the deformation of rock during the test.
