Safety and Reduction of Technology-Related Risks in the Process of Earth Dams’ and Dams’ Operation

Abstract

Ground water-retaining structures belong to hydrodynamically dangerous objects, most of the accidents are due to errors made during the design, construction and operation of structures, including insufficient ridge stock above the water level in the reservoir.The reason of the pressure front breakthroughs of three hundred dams in various countries of the world for 175 years was the overflow of water through the ridge of the dam (35% of cases).The article provides the tasks for improving, creating more effective technological and constructive measures to combat defects and damages of ground water retaining structures based on known, positively proven and improved technologies and technological processes that take into account the technological and financial capabilities of local repair and construction organizations and farms having machines and mechanisms and local raw material base at their disposal.
