The article presents the rationale and development of electro physical methods of control of the degree of soils pollution with petroleum products. The ranges of variation for the parameters of the pore space structure and wettability for the Kuzbass conditions are determined by inverse calculations on the basis of experimental data. The theoretical dependences are shown which allow us to assess the degree of soil pollution with oil products according to the results of longitudinal and areal electrical sounding. The study confirms the possibility of rapid prediction of the degree of soil contamination by measuring its electrical resistance. The database has been compiled for interpretation of the results of experimental sounding when monitoring the changes in the degree of contamination. The use of the express forecast of numerical values of the contamination factor was studied.

Therein there is formation of algorithms database of stress-strain state of reinforced soil foundations and optimizing the main parameters of the computer model. The analysis of the results of calculations for the foundation strip, slab and columar type on homogeneous and layered the basis.

Abstract. The emergency condition of the mine surface facilities including a coal wash plant, a crusher, a bunker and three galleries, is considered. As a result of a complex of engineering-geological and geophysical surveys, it is established that the significant deformations of the foundations of the structure are caused by the zones of weakened (unconsolidated) soil in the bases of the foundations formed due to landslide developments in the bulk ground mass. The article describes the techniques for justifying the technological parameters of the consolidation grouting of soil bases including computer modeling, forecasting of deformations of the natural and consolidated ground mass, analysis of the stress-strain state of soils in the most dangerous area. The effectiveness of the adopted scheme of consolidation grouting of soil bases according to the approved methodology for elimination of the emergency condition of the mine surface facility was confirmed. The limit values of the calculated horizontal deformations in the soil bases of one of the supports of the galleries are determined. To prevent the indicated deformations, it was recommended to provide an additional row of injection wells with a depth below the border of the loosened soil zone.

Herein there is a description of algorithm of the automated forecast of stability for soil slope structures including input of initial data regarding physical and mechanical properties and geometrical parameters of a structure, building of the most intense sliding face, computation of the slope stability by the polygon of forces method. Developed on algorithm basis, The Stable Slope software package has been implemented in open pit located in the Altai region. There are calculation results of the parameters of the Eastern steady side (slope angle at a given height) depending on the inclination angle of contact of the friable Quaternary deposit with a parent rock. Recommendations can improve work safety under adverse natural and man-made conditions causing formation of unstable water-saturated zones.

Abstract-This article describes methods and results of laboratory simulation of processes in the clay soils contaminated by oily substances in the samples, on the one-dimensional and three-dimensional physical models. It describes the laboratory setup, the procedure for conducting experiments and processing their results. The possibility of point and integrated prediction of the degree of contamination of the soil on the measurements of its electrical resistance was confirmed. The behavior of changes of porosity, moisture content, granulometric composition of soils contaminated with oil products when there are electrically treated due to thermal and osmotic effects was identified by comparing the data of direct measurements and of electrical control by the system of microprobes. The comparison of results of electrical treatment of the clean soil contaminated with liquid and viscous oil p;roducts, as well as by over-exposure to the active substance -solvent was given.
