The monitoring of the natural-and-technical systems «dumpfoundation»

In conditions of high cost of the land plots lease and restriction of their areas for overburden dumps placement, there are relief areas unfavorable, in terms of stability conditions, allocated, that increases the risk of deformations and violations of the stability of the dumps. By methods of the system analysis, risk analysis, as well as based on the results of the instrumental surveying monitoring, possible scenarios for development of the deformations and their probabilities, along with the scheme of deformation of the piled-up mass, have been established. In the article there are the results of experimental studies of the stress-strain state of the various types of dumps in order to detect the most vulnerable areas, where signs of deformations appear in the first place. It is figured out that schemes and mechanism of deformation of the natural and technical systems are determined by morphology of the natural and man-made relief of the earth’s surface. Taking into account schemes and mechanism of the NTS deformation, as well as experimental data obtained from the results of surveying monitoring, the design of the observation station has been developed, providing for the location of the benchmark rods in the weakest places, that makes it possible to detect deformations of dumps at an early stage and timely take measures to prevent landslides. The results of the research can be useful in substantiating the most hazardous sites as per the condition of stability, where it is recommended to fix bench mark rods of the observation station for geo-mechanical monitoring of the external and internal dumps, as well as bulk soil structures.
