| Abstract | The uniaxial compression test has been widely used for
the determination of uniaxial compressive strength and static
elastic modulus of rock cores, but requires machined specimens
and is therefore a slow techanique. Preparation of rock cores
is costl y and time consuming. Rock lumps can be easily
prepared even for weak rocks. Choosing ultrasonic pulse test
on rock lumps as a convenient and rapid method to estimate the
static properties is a fesible alternative.
Samples were collected from several locations in
Thailand. The ultrasonic pulse test was conducted on the rock
lump specimens. The dynamic elastic modulus of lumps was
calculated from the P-wave and S-wave velocity measured and
was compared with the dynamic elastic modulus of rock cores.
Also, the relationship between them was established.
Comparing the dynamic elastic modulus and point load
strength index of lumps with the results of uniaxia l
compression test, the properties in static condition can be
estimated. |
