Introduction With the expansion of national infrastructure investment, bored piles is widely used in highway bridges, civil construction, railways, airports, terminals and other application areas.Bored pile can apply to the groundwater cohesive soil, powder soil, sand, filling, crushed stone (gravel), weathered layer and soil which more complex geological conditions, interlining, erosional differentials, soft hard strata changes greatly[1].
(5)Check the final hole: When the drill reached the design elevation, the attention to check the geological strata, and to extract the rock residue compared with the design, if the pile hole dug to the design level, such as geological conditions and design match, made the final hole to check the supervising engineer; such as inconsistent change the views put forward by the design Institute.

For the development of this system, supported by the Technological Agency of the Czech Republic (see Acknowledgement), the firm Alumistr Hrušovany, Ltd., is responsible; its principal research partners are the Brno University of Technology, Faculty of Civil Engineering (FCE BUT), in the Czech Republic, and the Technical University in Lulea in Sweden.
However, the plate method brings serious difficulties or cannot be performed at all in the case of some material classes applied in civil engineering, namely to the powdery materials, creating no insulation layer with a constant thickness.
However, both the experimental and computational techniques sketched in this paper could be applied to a larger class of problems of high-temperature behaviour of materials used in civil, mechanical, etc. engineering, as in refractory brickworks or advanced materials and technologies for passive houses.

Abstract.
Proper design of structural system is the most important task for a structural engineer.
Proper design of the interaction between the building and the subsoil is very difficult problem and therefore it is very important for experts to cooperate, mainly for structural engineer and geologist.
All variants were evaluated using the software Scia Engineer 2008.
