However, the commonly used gravity foundation of wind turbine generator is usually controlled by the tensile stress of the bottom surface of the foundation, resulting in waste of materials.
For rock mass and concrete category of materials, although the use is not associated flow rule, it is more in line with the actual situation, this means that the material is unstable, and the export of elastic-plastic matrix is asymmetric.
For geotechnical materials, two kinds of models are mainly adopted for hardening rule: isotropic hardening and kinematic hardening.

Constructing the Framework of Coal Resources Paid Use System Xinwen Wu1, a, Wutao Lu2,b 1Heilongjiang Institute of Science and Technology, Harbin 150027, China 2Heilongjiang Institute of Science and Technology, Harbin 150027, China awxw1758836@vip.sina.com, bluwutao2007@sin.com Keywords: coal resources, paid use system, framework Abstract.
The mine resources paid system in Russia consists of three parts: underground resources use tax, consumption tax, and mineral raw materials reproduction fund deduction, the last is a particular method to Russia.
Mineral raw materials reproduction fund deduction, as the underground resource lax in 1992 and the article forty-four of the amendment say, it is levied from all the resource exploiters, and its profit is turned over to the mineral raw materials reproduction fund which is out of the national budget.
The mineral raw materials reproduction fund is used in regional development, geological survey, scientific research and other research about the underground resources, deposit survey and assessment, and so on.

However, in tunnels, surface paving material and technique are still limited to cement concrete.
Preparation of Flame-retardant Ssphalt Experimental Materials and Instruments.
It is generally believed that, when LOI ranges from 20%～27, the material is combustible; when LOI is less than 20％, it is flammable; when LOI is larger than 27%, it is self-extinguishable material in fire.
Asphalt mixture must be filled with some powder material.

Materials and Methods To analyse the impact of the filter cartridge design on the aerodynamic characteristics of the air flow entering the filter, numerical modelling was used in a three-dimensional Cartesian coordinate system based on the continuity equation.
This is due to the fact that turbulence often occurs at their edges, which develops an uneven distribution of air and increases the load on individual sections of the filter material.

Secondly, geometrical information, structural constructions and the material properties are to be investigated in details.
Investigation of Geometrical Information, Structural Constructions and Material Properties For historic buildings, the material properties are usually deteriorated to some extent, and the design approach as well as structural constructions may not meet the requirements of current design and construction codes.
The investigated mechanical properties of materials should be applied in the above analysis procedures.
The design strength of materials fd was calculated using Equation (1) (MoHURD and GAoQSIQ 2005), d df fγ= (1) where f means the investigated material strength under static load, and γd means the comprehensive adjustment factor for material strength under dynamic load.
