In recent years, with the rapid development of seismic theory of underground subway structures and computing technology, the numerical simulation analysis can fully display the dynamic properties of underground stations, interval tunnels and other ground structures in the earthquake action, so it is widely used by scholars all over the world.
As for the ground structures, the earthquake acceleration is the main factor that affects the structural dynamic response
The dynamic response of the structures depends on the shape, size, quality, rigidity, and the physical properties of the foundation.
Besides, it cannot be restrained by any geometrical conditions and properties, but for a high accuracy in the partial space and time domain.
The ordinary shaking table test is in a fixed acceleration field, and there exist lots of factors that affect the test outcomes, which have a direct influence on the simulation effects.

The analysis of the surface properties on the slip resistant of the treated surfaces was equally done and it was observed that the hardness and roughness of the alloy affects the coefficient of friction via comparative studies [16].
Also, established that Alloy steels are stronger than normal steel due to the alteration in their mechanical and microstructural properties.

Recently, with the introduction of probability concepts in the design of coastal structures, the probability density function (PDF) of the tidal elevation has considered as a very important design factor [1].
In this case, the PDF of tidal elevation is a very important factor for the ecological analysis of the flooding and exposure times that determine the habitation zones in the intertidal zone [2,3,4,5].
A change of sea level from climate change, may affect the coastal zone [6].
Therefore, when it comes to judging the statistical property of tidal data the reliability design under the assumption that tidal elevation data is considered to have a normal distribution, the assessment may include the error.

As can be seen from Figure 2, it is evident that premixing methanol along with intake air of the engine dramatically affected the pilot diesel ignition delay period, in-cylinder pressure and PRR.
These factors resulted in decreasing NOx emissions.

The HTC depend on many factors, in relation to the state of the interface.
It is generally recognized that alloy temperature [1,2], formation of a shrinkage gap [3], chill temperature, surface roughness and chill material [4] all affect the heat transfer.
An explicit finite difference solution to the one-dimensional inverse heat calculation program [7, 8] was used based on a non-linear estimation method, which can be used to deal with the phase change and temperature-dependent thermal properties of solidification processes.
Anyway, a general increase in the whole cooling efficiency can be depicted without doubt, with interesting consequences for the design activity of sand casting processes and in order to obtain the best mechanical properties on the final product.

Building the constitutive model considering particle breakage Soil is the mixture of rock broken of weathering and mineral grains, the stress-strain relationship is complex, and related to many factors.
Yao Yangping [19] established constitutive model of sand particle breakage based on the affect of granular material particle breakage on the material dilatancy characteristics.
All the parameters can be determined by test with clear physical meaning, and can describe the mechanical characteristics of sand particle breakage reasonably.
With the building of high-heavy earthwork construction such as high dam, the soil particle breakage phenomenon in the high stress brought about the mechanical properties of the soil can not be ignored, the constitutive model considering particle breakage become the focus of current research projects.
