| Summary: | 碩士 === 國立臺灣科技大學 === 營建工程技術學系 === 84 === Generally speaking, the temperature and pressure of rock mass
will increase as rock depth increases. The mechanical behavior
of rock may be different as temperature and pressure change. In
order to understand the behavior change due to temperature and
pressure, Hua-Liang Marble was used in the research.
Cylindrical marble were heated at different elevated
temperature, and the Brazilian and triaxial compressive tests
were performed. The stress-strain curve, tensile strength, post-
peak stress-strain behavior, shear strength parameters were
analyzed under different elevated temperature and confining
pressure. The angle of the internal friction of Hua-Liang
Marble shows little change within 300 .degree. C. The brittle-
ductile transition pressure of Hua-Liang Marble at room
temperature is about 40 MPa.
