摘要：
GeoSea n.v. is currently working on the development of windfarms requiring piles to be installed in hard clays and weak rocks. Drilling is required for pile installation and to optimize the installation it is preferable to drill without internal support measures. The authors have reviewed methods for assessing the stability of large diameter boreholes drilled in rock. Borehole stability is modelled using finite element modelling software PLAXIS 2D with the Hoek and Brown constitutive model. Results from these calculations are compared against methods from mining industry and well stability methods.
