This article proposes the method of the registration of the parameters of a geotechnical system. This method is designed to increase the efficiency of the functioning of geotechnical monitoring systems in the condition of the risk of the disturbance of the geodynamic stability and in the condition of technical and economic restrictions when monitoring works are organized. The proposed method allows you to select the technical parameters of the monitoring system and it allows you to select monitoring points in the geotechnical system based on economic indicators. The selection criterion is the criterion of minimizing the costs of introducing the geotechnical monitoring system with respect to possible damage, which is expressed in monetary terms, in case of the disturbance of the stability of the geotechnical system or its analyzed area. The costs of implementing of the geotechnical monitoring system are determined based on its cost, fixed costs for its maintenance, as well as technical parameters. Costs of introducing of the geotechnical monitoring system are determined by the next technical parameters: the costs are highlighted in the case of missing destructive geotechnical processes, costs are in case of false operation of the system and costs of registering one parameter of the geotechnical system at one point by a specific method. It is proposed to carry out measurements at key control points for reduce the number of monitored parameters and measurement points. The choice of controlled parameters is carried out on the basis of the bifurcation approach. The practical check of the developed method of the registration of parameters of the geotechnical system was carried out during the detecting of suffusion processes in urban areas in the city of Murom, Vladimir Region, Russian Federation. The proposed method allowed to significantly reduce the cost of monitoring work while maintaining the accuracy of results of the work of the monitoring system.
