Experimental design to investigate the dependence between the coefficient of compaction and the modulus of deformation
There are five basic methods of mechanical soil compaction: rolling, vibration, compacting, vibrocompacting and combined method. Regardless of the type of soil and the chosen method of sealing, special attention should be paid to the quality control during the work. The main controlled parameter when performing any soil compaction is the coefficient of consolidation. In calculating of settlement buildings the main characteristic is the modulus of deformation. Thus, we can conclude the necessity of obtaining the dependence between the coefficient of compaction and the modulus of deformation, that is, to find the dependence between the main parameter controlled about the production of works and frequently used in the design. The article is planning a series of experiments to find this dependence. In the first phase of the study, regardless of the test conditions (real object or experiment in the tray), planned determination of the maximum density and optimum moisture content in accordance with GOST 22733-2002 “Soils. Laboratory methods for determining the maximum density” for subsequent determination of compaction factor. Next, after determining factor compaction is planned to take samples by cutting ring for compression testing with subsequent determination of the compression modulus of deformation in accordance with GOST 12248-2010 “Soils. Laboratory methods for determining the strength and strain” in accordance with para. 5.4. The tray is planned to reach values of the compaction factor of 0.92; 0.95; 0.97. For each factor is necessary to seal at least 6 compression test, for a total minimum quantity of 18 pieces of samples. According to the tests will be compiled summary tables of values and plotted the compression ratio of the compression module.
