"The rough surfaces of cement based materials which are jointed with the irregular surfaces of rocks in the foundations of large civil engineering structures represent critical parts considerably influencing mechanical stability of those structures. The mechanical strength of these joints strongly depends on the roughness (asperity) of both the surfaces. This roughness is an important factor when the stability of large structures such as dams, bridges, tunnels, etc. is estimated. The present proposal is aimed at developing a new method for classifying morphology features of solid surfaces to facilitate estimation of their roughness indicators. This will be conceptually new method which will be able to distinguish between different types of two-dimensional Fourier wave modes that are formed on fracture surfaces. For this purpose a new hardware for digital surface reconstruction will be designed and built."@en . . . " cement-based materials" . " digital three-dimensional reliefs" . " surface morphology" . . .
