| Abstract: | It is necessary to determine the moduli of elastivity of rock for modelling and predicting well trajectory of directional drilling. In this paper rock is regarded as transversely isotropic and the constitutive equations of rock were presented. On the basis of the principle of electrical-resistance strain gauge, an experimental method was developed for measuring five moduli of elastivity of rock and several measuring results were given. |
