The influence of experimental studies on the stability of hydraulic structures

Abstract

The article shows the main causes of accidents dams, including the effect influence of the undermining of territories. The aim of this work was to evaluate the possibility the formations in the model of the dams a cracks with certain areas of their distribution, as well as the degree of influence of reinforcement on their overall stability. Failure analysis shows that the reliability of these types of structures is different and depends on the uptime of individual subsystems. For soil dams, the largest number of failures is associated with filtration problems in the body and foundation of the dam during emergency floods. The decrease in stability and the increase in the development of crack formation during deformation of the soil base is greater, the greater the horizontal and vertical deformation of the soil. The effect of the reinforcing effect during stretching of the soil base, i.e. reinforcing the soil dam with geotextiles significantly affects the increase in stability and the decrease in the development of cracking during deformation of the soil base.
