Engineering projects such as nuclear waste disposal and deep tunnel under high mountain may involve site condition of great depth underground. As depth at considered site increases, both the underground temperature and pressure tend to elevate. The mechanical properties of rock at elevated temperatures and pressures can be significantly different from those, which are in the room temperature condition. To evaluate the creep properties of rock at elevated temperatures and pressure over a typical type of rocks is selected as tested material in this research. The types of mechanical experiments include uniaxial and triaxial creep tests. Based on the understanding of the mechanical behavior, endeavor will be contributed to establish a material model, which is able to describe the characteristics of rock. The expected results of this research are able to obtain the creep behavior of rock at elevated temperatures and pressures.application/pdf546293 bytesapplication/pdfzh-TW國立臺灣大學土木工程學系暨研究所砂岩潛變sandstonecreep[SDGs]SDG15reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/2844/1/922211E002047.pdf
