The present paper is concerned with the development of calibration program for the Von Wolffersdorff hypoplastic model, often referred to as the hypoplastic model for sand, and as such to bring this model to the point of practical applications. The proposed methodology combines standard laboratory measurements with their numerical simulations at a material point to address, apart from experimentally derived data, those model parameters which can be inferred from theses laboratory tests only indirectly. As an example, the entire calibration process is presented for a sand sample collected from a construction pit of the Komořany tunnel.
