Model of calculation On the basis of the past experience and the practical conditions, some hypothesis are established for the FEM model as follow: (1) the stress-strain relationships is satisfied to the basic hypothesis of plain strain problem; (2) the anchor bolt and lining are belong to elastic materials, but the rock mass and soften joints are considered as elastic-plastic medium; (3) the normal of the isotropic surface is orthogonal to the axis of underground opening.
The deformation modulus of interfaceequals to 500kpa, equals to 400kpa andequals to 50000kpa, other material parameters are shown in Tab.1.

Introduction Electrospinning is a plain and wide process for fabrication of an ultrafine fiber from various materials which include polymer, composite and ceramic.
The most preferred fiber/material in various applications is a fiber with a diameter within 10– 1000 nm in scale and soft surface morphology.

There are different types of insulation materials for applying on a new roof or retrofitting an existing structure.
The measured density and thermal conductivity values of various insulating materials are given in Table 2.
As there are many thermal insulating materials available, its selection is dependent on the thermal conductivity, thickness and typology of walling and roofing materials.

Introduction Physical modification of the existing polymers, their combination with materials of different nature and structure with the aim of attributing a specific set of qualities to a polymer which would be dependent on the type of the inclusion represents one of the promising ways to solve the problem of production of new polymer materials – the so-called polymer composite materials (PCM).
The PCM according to their functional characteristics could be divided into construction materials, i.e. the polymer materials with the improved complex of mechanical properties, and the materials with specific properties: a certain level of thermal conductivity, conductivity or some other electrical features.
Such behavior of the composite polymer materials based on polyethylene and polypropylene could be explained by the peculiarities of conductivity of these materials.

Resene glue materials and carbon fibers are pasted on the surface of concrete structure, in order to achieve the purpose of reinforcement of structural components and the improvement of mechanical properties.
In order to meet the requirements of safety, we used the CFRP materials to reinforce the original structure.
After theoretical calculations, we get the following conclusions: (1) The experimental results show that reinforced concrete beams paste with CFRP have significant reinforcement effect, and the ultimate bearing capacity has been improved after reinforced with CFRP materials
