Safety is the core of the railway transport [4].
Once the train speed reached 200km/h or more, even smaller disasters or accidents is also likely to lead to a major traffic accident on the railway, it seriously endanger the safety of state property and the lives of the passengers[7].
The train locomotive and 1-4 vehicles had derailed, the accident caused four deaths and 71 injured, Jiao Liu line interrupted traffic whole line.
It is a threat to railway lines and train traffic safety.
When monitoring specific work sites, we should be investigated local topography, environment, climate and safety level types to choose reasonable monitoring means. 2 home and abroad development status of the foreign matter invasion warning system With the growing national degree of attention on railway safety, related railway departments keep train safety as a priority and study the relevant safety technology as an important part of the high-speed railway construction.

With the enhancement of safety factor in civil aviation, simulation technology has been paid more and more attention and got comprehensive application.
At present, the mainstream international simulation software, such as Vision, CEFA [3], can achieve simulation and reconstruction.

In operation phase, the traffic pollutions (noise, electromagnetic) have a significant impact on the lives of residents.
Therefore, in this phase the inventories includeSocial environment (U51) with three third-class indicators of living, traffic safety and employment; Ecologicalenvironment (U52) with three third-class indicators of natural landscape and cultural relics, effect on animals and vegetation deterioration; Surface water pollution (U53) with nine third-class indicators of SS, COD, NH3-N, BOD5,petroleum, pH, hydrology, SO42- and Cl-; Air pollution (U54) with six third class indicators of CO, CO2, SO2, NOx, CnHm and TSP; Solid waste (U55) with a third-class indicator of industrial solid waste;Noise pollution (U56) with two third-class indicators of mechanical noise and traffic noise.

The indexes of the top three highest impact strength to ecological environment are: "the coordination coefficient of economy system and environmental system", "population space density", "traffic pressure".
There are five cities in the “rather safety” grade.
The "ideal safety", "relatively safety" grades of ecological environment is low, while the "unsafety" and "less unsafety" probability are higher.
In contrast, those "safety" and "rather safety" cities are located in advanced economic and social regions.
