Study on Rock Strength Characteristic by Point Load Test

Article Preview

Abstract:

Test point load test requires relatively small load, its instrument is portable, it can be easily applied to on-site testing,which may pave the way for the development of the fieldstrength of rock mechanics test, widely promoted in engineering construction, has a large space for development. When selecting the uniform rock do the load and saturation points uniaxial compression test respectively, and comparing the analysis of the two trials correlation between the results obtained by the method, the results showed that: point load test as a qualitative and semi-quantitative indicators are needed to meet the requiement of project, but if we put it as a fully quantitative indicators ,which will lead to large errors,and even lead to sweeping errors.
