Na fyzikálních modelech byly speciální metodou měřeny deformace tunelové čelby při různých stavech zatížení a v závislosti na délce záběru. (cs)
Physical models from equivalent material were constructed and deformation at the tunel face was measured at stages of loading and commensurate with length of purchase by the special method.
