Filtration model of the rock foundation of the dam pressure

Introduction. Presented the approach to the create a filtration model of the base of the hydroelectric system, built by mathematical and statistical generalization of the results of mass filtration testing of the rock mass. In the proposed filtration model, the rock base is divided into several engineering-geological design elements with different permeability. Materials and methods. The most common approach to build the model is determine the points of the array hydraulic pumping and injection of water into the well, as well as by calculation, when the filtration coefficient of the array is calculated on the parameters of cracks. Results. One of the advantages of the proposed form of the filtration model of the rocky foundation of the hydroelectric complex is the form and method of its construction by means of mathematical and statistical generalization of the results of mass filtration testing of the rock massif. Conclusions. In of civil engineering the filtration model of the base of the hydraulic unit can be built on the results of the poson filtration testing of drilling wells at certain points of the rock mass. The difficult task of dividing the base massif into zones with different water permeability is solved on the basis of a geological-genetic approach in combination with mathematical and statistical analysis. The practical significance of this filtration model is that it can be used to design reliable hydraulic structures while ensuring stability and minimizing filtration losses.
