Modelling of the rock structure stress field near the cavities and estimation of the cavity effect influence on the tidal measurements

Kostecký, Pavel; Kohút, Igor - In: Mathematics and Computers in Simulation (MATCOM) 50 (1999) 1, pp. 205-214

The article is dealing with the problem of cavity effect influence on the tidal measurements in geophysics. The measurements of tide-induced deformations and tilts are usually performed in underground cavities. The data obtained must be debugged of the influence of the cavity itself (cavity...
