Based on Web-services platform, the departments can use relevant Web services according to needs, such as the disaster area road information, personnel information and materials information, to combine the appropriate emergency procedures, timely and efficiently complete the emergency task.
Several cases of China's nuclear accident occurred are due to lax supervision and incomplete detection of nuclear waste, which made the common people can’t recognize the nuclear waste and view them as ordinary garbage or recycling materials, resulting in varying degrees of injuries.

Material parameters.
Except for that backfill soil was taken with homogeneous elastic-plastic model, the rest are all the materials to the homogeneous linear elastic models.
The relevant parameters of all kinds of material were chosen based on the engineering geological data and some relative rules [6], and the detail parameters of the material were shown in table 1.

In this simulation, a temperature-related elastic-plastic material model is applied.
Considering the influence of temperature on the mechanical properties, basic material parameters relating to temperature are needed to define in the thermal mechanically coupled calculation for rolling process, such as density, density, elastic modulus, poisson ratio, yield strength, at the same time the basic thermodynamic parameters are also needed to define, such as the specific heat and thermal conductivity.
The material of 60kg/m rail in this simulation is U75V, its basic parameters are plotted in figure3, and the density of U75V is 7721 kg/m3.
