In addition, through the rational design in a modern car, with application of new lightweight materials, such as high strength steel,1 aluminum and magnesium alloys, titanium alloys, engineering plastics and carbon fiber, rare earth and other polymer and composite material to replace the traditional iron and steel materials would also be of an important ways to reduce the automobile weight, with ensuring high-speed vehicle stability and security of the premise as well as[1].
As well as, we must adhere to the technology path in that, structural design, a variety of materials and manufacturing techniques are integrated, which is the key of resolving the problem of lightweight and security.

The choice of similar materials and the design of mix proportions is a key step in landslide model test.
By analyzing the result of mix proportions test, We concluded the regularity that similar index varies along with different content of the similar material ingredients and found the notable influence factors , which provides important reference for the components of similar materials in the landslide model test. 1 Instruction The landslide physical model test is a direct and reliable research method in the study of landslide failure mechanism, and how to choose the similar material and its mixture is the key to the success of model test [1].
In addition, in practical engineering application, most landslides were caused by the effect of rainfall infiltration and reservoir water, so we should also take the similarity of permeability into consideration.
