Keywords: corrosion resistance; X52 pipeline steel; sea mud; corrosion products.
Generally, soils with high dissolved salt, high resistivity and high acidity are more aggressive towards metallic materials.
Yan et al reported that the representative of red clay soils in South China were extremely aggressive towards various metallic materials, and the corrosion rate of carbon steel in this kind of soil was above 0.1 mm/year, classified as the severe or very severe level [2].
X52 pipeline steel is one of the main pipeline materials because of its good ductile fracture resistance ability and corrosion resistance, which is widely used in natural gas, hydrocarbons and crude oil transport industry.

Because the crystal X ray diffraction and magnetic materials were used in residual stress measurement, it had no material separation or machining, and it could directly measure residual stress.
The penetration depth of X ray in the iron, steel or other metal materials was about 10, therefore it only could measure the residual stress on surface.

According to the regulation about material properties in Load Code for the Design of Building Structure, parameters and element selected as table 2-1 below.
Figure 1 SOLID164 unit is a kind of 8 nodes unit Reductions (single point) integral and stickiness hourglass control have been applied at the default in order to get faster unit algorithm. 2.2 material model and constitutive relation Masonry is a biphasic composite material composed by blocks and mortar, reinforced concrete is a biphasic composite material composed by concrete and rebars, there are usually 2 types of models to do the finite element analysis: disjunctive model and whole continuum model.
The second way of modeling is used here, according to the constitutive test of masonry in reference[3] and the material introduction in reference[4] , masonry and reinforced concrete material in composite structure are all modeling as bilinear isotropic material.

Design of public facilities should consider the city geographical location, climate and other natural environment, pay attention to the harmony and unity of facilities and the natural environment[2].Designer should comply with nature, but also control the use and transform nature, and through the reasonable selection of materials, color, shape, make the public facilities, city landscape and the natural environment to achieve "harmony between man and nature" (the harmony and unity of the natural environment and human's life).For example: cold and dry climate in the north,in order to adjust the long monotonous colors in winter,the materials of public facilities should be used with warm texture of wood,and the color of public facilities should be bright eye-catching.
Warm and rainy in the South, the selection of materials should be paid attention to moisture rust, and be used of plastic or stainless steel material.The color should be also dominated by bright colors.
Because public facilities is an important part of city landscape, its role is in addition to its own material function, but also its ornamental and image.

To elaborate on the concept of uncertainty propagation, consider a complex component incorporating inelastic materials, contacts, friction etc.
The model requires an initial specification of material properties, clearances and friction coefficients.
