Abstract
The authors propose the approach to validation of the surveying control accuracy in safety monitoring of earth dams in terms of liquid waste receivers at mines. Based on the system structuring of types of earth dams and their elements, estimation of influence of loads and effects exerted to these structures, as well as the analysis of accident risks using the Hazard and Serviceability Analysis, an ideal sign model of earth dam safety monitoring has been constructed and the scope of field observation has been specified to record hazardous off-sets and prevent hydrodynamic accidents. By modeling an ideal earth dam, the authors determine the dam stress–strain state criteria. From the condition of non-admittance of limit equilibrium disturbance of the earth structure, the requirements on the accuracy of horizontal and vertical surveying control over structural elements of dams are set.
