Consideration of the influence of the initial stress state of rock bases of hydro-engineering structures on models from gypsum porcelain composite

Methods of researching the stress-deformed state of rock foundations of hydraulic structures are analyzed, laboriousness and costliness of large-scale natural studies in field conditions are emphasized. Rock foundations are a natural composite with an initial stress state, and its influence on the deformability of the foundations of hydraulic engineering structures is one of the most important issues of interest to the scientific world. The strength and deformation indicators of the gypsum-lime composite under compression and tension loading were determined on the samples. Based on the developed method of the stamp on a flat model made of gypsum-limestone composite, the experimental data show the influence of the experimental values of the modulus of deformation determined by the method of loading the rocks with the stamp.
