Modern production technologies are "short-lived". They quickly progressed continuously increasing knowledge-based, requiring all engineers, included in the process, not only the ap- propriate level of intellectual development, but scientific and social development, which ad- vance and give an opportunity to see and evaluate the possible options for follow-turns technological. The ability to predict the processes of technological and social development become vital for the competitiveness of engineering and technical professionals. It requires continuous training and psychological self to the success of the subject in the new environment.

The article presents the results of analytical numerical calculations of the cruciform foun- dations under the uniformly distributed load. The distributions of the stresses and displace- ments in active zone of the cross-shaped foundations are featured. The comparison of experi- mental and analytical settlements of complex form foundations is carried out. Multifactor power dependences are gained to define the settlements of cruciform foundations on cohesive and non-cohesive soil basement. The ability of the effective foundation forms using the condi- tion of the maximum allowable settlement is featured.

In the past few decades, the method of final elements was wildly used in testing stress- strain state on computer building structures. As a rule, discrete final element's model of any structure consists of the final elements number of different sizes, which are joined to each oth- er. Wrong docking of badly compatible final elements leads to deformation of calculated model generally and as a result to wrong calculation data knowingly.This problem was especially acute in the early stage of development of numerical methods, and it is relevant today.The author of the article intends to return tothe discussion of this issue. As the object of study, concrete ribbed slab was considered there, for modeling which required using different types of final elements.

Thick-walled shells are found in many engineering structures, particularly in the con- struction of thermal power. Another example of practical application is the design of storage facilities for cryogenic liquids. We consider the problem calculating finite cylinder which is in an axisymmetric tem- perature field, the material of which has a non-linear stress-strain diagram. Chart options depend on the temperature

FE size influence upon the design stress-strain state of arch dam is investigated keeping in mind the mathematical substantiation the effectiveness of constructive solutions to strengthen the structure

In the paper, results of studies of estimated characteristics of grounds in saline areas of Uzbekistan used in the sub grade soil construction of automobile roads are given. As the result of interpretation of experimental data, the graphic analytical dependences for determination of estimated characteristics of grounds according to the type and quantity of salinization, density, and humidityof soils were derived
