| 英文摘要 | The tensile elastic modulus E(t) of a rock is different from the compressive elastic modulus E(c), due to inhomogeneity and microcracks. There is no convenient method to obtain E(t) except using direct tension tests. However, the direct tension test for rock materials is difficult to perform, because of stress concentrations, and the difficulty of preparing specimens. We have developed a new method to determine E(t) of rock materials easily and conveniently. Two strain gauges are pasted at the center part of a Brazilian disc's two side faces along the direction perpendicular to the line load to record tensile strain, and a force sensor is used to record the force applied; then the stress-strain curve can be obtained; finally the E(t) can be calculated according to those related formulas which are derived on the basis of elasticity theory. Our experimental results for marble, sandstone, limestone and granite indicate that E(t) is less than E(c), and their ratio is generally between 0.6 and 0.9. (C) 2008 Elsevier Ltd.
