Placement of wells in the floor plan should provide assessment of heterogeneity of soil strata, and also take into account structural features of the building and the distribution of loads. 2.7. As part of research should include the implementation of static sensing refine engineering-geological grounds between the wells, the identification of heterogeneity of soils, their strength and deformation characteristics, as well as assessing the bearing capacity of piles. The number of probing points shall be not less than ten, and the detection of significant heterogeneity and complex ground conditions, this number should increase. 2.8. The composition of the work in prospecting should include a geophysical survey for refinement of the geological structure of the array of soils between the wells, in particular the determination of the depth of the karst rocks, fracturing them and karst, the presence and thickness of layers of weak soil and aquitard, direction and speed of groundwater movement. 2.9. To determine the deformation parameters of soils is necessary to provide field-tested cliches in an amount not less than three or pressiometrami in the number of at least six for each of the selected engineering geological elements.
Program of field trials should include the identification of modules with total and elastic deformation, respectively, over the branches of the loading and unloading schedules 'Sediment-load'. 2.10. Laboratory studies of soil should model the work of the soil at the base of the building in a changing stress-strain state. In particular, testing the soil in the compression apparatus and instruments necessary to carry out triaxial compression view of the natural stress-strain state of soil mass and structural strength of soil in the range of operating at the base of the building stress and provide soil samples and record the history of loading volume of soil in nature.
