Summary: | 碩士 === 國立交通大學 === 土木工程研究所 === 82 === The stress distribution in anisotropic rock masses is strongly
dependent on the degree of rock anisotropy which can be
represented by the elastic contants of the rock.In order to
evaluate the stress components in anisotropic rocks,the
elastic contants have to be obtained. The five elastic
constants of two types of transversely isotropic rocks,
argillite of Ken-Guo formation and slate of Lu-Shan formation
in central Taiwan and northern Taiwan, respectively,are
obtained by conventional uniaxial compressive testing on
cylindrical samples at laboratory in this experimental reseach.
The results show that the five static elastic constants of
argillite are E=51000 MPa,E''=32000 MPa,v=0.19,v''=0.18,
G''=13000 MPa, and those of slate are E=54000 MPa,E''=22000 MPa
,v=0.19, v''=0.12$,G''=15000 MPa.It is found that the degree
of anisotropy of slate samples is larger than that of argillite
samples.This phenomenon shows the difference of metamorphism
degree of the two diffenerce types of rocks.
