The existing chemicals environmental legislation should be perfectd for the weak links of the current chemicals management laws and regulations, it should also integrated with the international chemicals management.
The establishment and implementation of the dangerous chemicals safety labels and safety technical specifications,so the units and individuals should grasp the emergency treatment and the mutual rescue measures.

The impact came with collision not only damages bridges and vessel, but also interrupts the traffic, or even has greater effect on casualties, environment, society and so on.
The international bridge and structural engineering association (IABSE) held an international meeting to discuss the issue in 1983, and then published the relevant design guidelines of vessel impacting bridge in 1991 and in 1993[2].
The analysis results are capable of providing theoretical basis for the safety assessment of the bridge and further bridge anti-collision design.

The results can provide some basic data for the mitigation of environment vibration arising from traffic loads.
Introduction With the development of urbanization and increase of urban traffic volume, the footbridge has get extensive application in a large densely populated urban area and main road.
Compared with the traditional methods, it has advantages of a reduction in the height of the main girders, the saving volume of work, the lithe outward appearance and the high degree of safety, but also there is a limitation in construction costs [2].

In the data analysis module, it can evaluate the bridge safety and generate testing report through the comparison of the corresponding curves between the displacement and working positions.
It is an important indicator reflecting the bridge structural safety.
