Yakovlev V. Determination of bearing capacity of prismatic piles by strength indexes of soil

Object - driven prismatic friction piles in clay and sandy soils; the purpose - determination of bearing capacity of driven prismatic piles by strength indexes of soil; methods - standard and speedy laboratory methods of determination of phisical and mechanical indexes of soil, the mathematical statistics methods, standard methods of static loading tests; method of ultimate elements for modelling of stressed-deformed state; novelty - the method of the driven prismatic piles bearing capacity according to the strength indexes of soil was improved; the separate determination of the soil strength indexes around the pile shaft and under the pile tip by means of treatment of direct shear tests of pre-consolidated saturated samples according to the method of total logarithmic reorganization and standard technology was suggested for the first time; the method of determination of settlement out of the linear soil deformation limit for the pile permanent cross section was improved; branch - building
