LABORATORY MODELLING OF FILLING PILE
Description
The grounds of modeling of filling pile static resistance have been offered so as the results of its realization at the laboratory models. The laboratory testing data are compared with the data of field testing of natural piles. The experimental and the model calculated values of bearing capacity shows the correlation coef-ficient 0,692. The laboratory tests confirm the exis-tence of the local maximum of the settlement “accele-ration”. The point of maximum proposed separates two stages of bearing capacity increment process: the stage of lateral surface mainly resistance and the stage of pile bottom mainly resistance

APPLICATION OF THE ROLLED CONCRETE IN WATER ECONOMIC BUILDING
Description
In the article the experience of application of the rolled concrete at building of constructions is described and bases of modeling of manufacture of plates from rigid concrete mixes are given
-
THE CALCULATION OF THE FOUNDATION SETTLEMENT OVER THE PLATE INVESTI-GATION DATA
Description
The basis of foundation settlement modeling over the plate testing has been offered. The similarity criteria were formulated so as the formulas for settling incre-ments calculation versus to setting pressure increments on the base of foundation. New principle of admissible pressure on the base of foundation has been suggested

Description
Hydraulic design of water outlets installed (mounted) on water application pipelines of low-pressure small-jet irrigation network when growing gerbera flowers under the conditions of protected ground is given in the paper. Relationships for estimating coefficients of hydraulic resistance and discharge coefficients for different nozzles are deduced
