Operating experience of concrete with vigorous motion of heavy vehicles has shown that, despite the high strength concrete slabs themselves, they need a strong base.When concrete is close to the ground in it, as a result pushes elastically flex when the aisles plates vehicles accumulated residual deformation.Initially, under the plates formed cavity plate lose contact with the ground, and then these cracks.The increase in base strength increases the cost of the pavement.

In this paper, a iphone 14 price san francisco static analysis of rectangular plate on two-layer elastic foundation in the traditional setting.As the base, taken homogeneoussoils, with the upper and lower layer in the form of half-spaces.Considered plate loading variant symmetrical about two axes from the calculated external load wheels.The calculation is performed by B.

N.Zhemochkina using symbolic mathematics package.When this plate was divided into 72 red pygmy dogwood rectangular portion in the center of which was placed vertical brace, through which the elastic plate contact with a base.The resulting statically indeterminate system, calculated by the method of mixed structural mechanics, where efforts were taken for unknown in vertical connections, as well as linear and two angular displacements inputted pinching plate along the axis of symmetry.

Coefficients of the unknowns related efforts B.N.Zhemochkina determined by the method described previously by one of the authors.The calculation of the vertical plate prepared surface displacements reactive voltage across the contact plate and an elastic base.

The proposed approach can be used to find the optimal solutions to (sufficiently) base strength to the estimated vehicle as well as for calculations hinged precast concrete plates.
