| Abstract | ||
| The paper presents the experimental study of mobilizing friction between soil and concrete. The series of laboratory tests have been carried out on coarse and fine-grained soils. Using statistical approach, the best fitting relationships describing the mobilized friction dependence on displacement have been determined for different soil types. It was found that the behaviour of sand soil unlikes that of clayey soil, so for each type of the soil behaved differently regarding the mobilized friction and displacement. In addition to that, the critical horizontal displacement, at which the whole friction is mobilized, is larger for fine sand than coarse one. The critical horizontal displacement for the normally consolidated clay exceeds more than twice the value for sand. The overconsolidation ratio for clay soil increases the mobilized shear resistance and reduces the displacement | ||
