In numerical calculation, concrete lining materials, insulation materials and rock materials are using plane strain quadrilateral element; anchor is using bar element material.
The concrete lining material and the rock mass are considering as linear elastic materials, while insulation materials is considering as Mohr-Coulomb materials.
Calculation parameters of materials are shown in Table 1.
Two sides of the roadway insulation materials generate compressive stress area, and the maximum compressive stress value is 389.36kPa.

Hence interest has been arisen in the development of alternative materials without asbestos for building [6-9].
Raw materials(cement, quartz, wood fiber and additive) in certain proportion were dry mixed with High-speed blender, and the stir time was 5 min. ②Wet mixing of raw materials.
After dry mixing, the materials were poured into mortar mixer, then water and MC were added gradually while still mixing, and the stir time after all materials added is 3 min. ③Compression molding.

Introduction 6061 aluminum alloy is widely applied in aeronautic, automobile, electronics and communications industries as one of structural materials because this alloy has excellent properties such as low density, moderate strength, good hot-workability and good corrossion resiatance [1,2].
And subsequent treatment can furtherly enhance mechanical properties to satisfy the needs of structural materials. 6061 alloy is one of deformation aluminum alloys, which contains magnesium and silicon as major addition elements and can be strengthened through heat treatment [3-4].
Material and experimental The experimental samples were taken from extruded 6061 aluminum alloy bar.

Vivid colors and complicated patterns are always adopted in such decorative textiles of various patterns, forms, materials, colors and applications.
Rlung-rta (Prayer Flag) Fabricated from source materials of cloth like brocade, thin silk, damask silk, silk and paper in white or five colors of blue, white, red, green and yellow.
Experimental section Materials.
Besides the above materials, it can be found that colors and patterns are more important for decorative textiles in Tibetan religious ornament arts.

Oxide glasses such as borate, phosphate, silicate and telluride have proven to be the suitable host materials for the advancement of optoelectronics devices due to their high transparency, easy to prepare and low cost production [4].
The raw materials as lithium carbonate (Li2CO3), aluminium oxide (Al2O3), ammonium dihydrogen orthophosphate (NH4H2PO4) and europium oxide (Eu2O3) were thoroughly mixed and ground in porcelain crucibles for 20 g total weight of glass samples.

Some scholars believe that the development of science and technology affect human survival homes, science and technology is a double-edged sword, the achievements of the application process changed the natural material cycle which cause some point imbalance and environmental problems. other view is that the human production mode has great effect on the surrounding environment, In order to pursue the interests human have adopted the destructive mode of production, the pollution events occur frequently, the ecological environment worsening, which cause serious damage to the human survival and development.
In the discussion on causes of environmental problems, negative effects of consumption on the ecological environment are widely ignored due to  the high degree of personal freedom and private concealment, which can promote economic and social development, increase the employment rate, bring enormous material wealth to mankind.
Third, the rapid growth of symbol consumption demand With the development of social productivity, consumption is more and more changed from the reality, the satisfaction of material to a kind of psychological satisfaction.
The product quality, grade, physical property, services and other material (functional) traits tend to fade out of sight of the consumer .Because of highly developed scientific and technological level, the frequency of product technology innovation, increasingly improving marketing skills ,people pay more attention on meaning (symbolic) of certain products than functional product.
