The rapid growth rate of automobile production and sales results in automobile energy demand surging and the proportion of car energy consumption in the total energy consumption is increasing. [1]According to statistics from the national development and Reform Commission, 97.5% of gasoline consumption and 52.1% of diesel consumption are for the supply of all kinds of traffic tools in China.
In China, the life and safety of power battery have been improved rapidly, and car motor industry started earlier than the power battery industry, but in the two fields there is still a gap between us and Japan, which is of the highest level in the world.
In case of serious traffic accidents leading to fuel leakage, diesel passenger cars will rarely burn or explode, and with a higher reliability.
The vehicle weight reduction technology is widely used by the traditional international automotive power in various fields of automotive design and manufacturing, and which have made a number of achievements.

However, frequent earthquakes severely endanger the safety of these reservoirs and theirs downstream.
Earthquake decreases the safety state of reservoirs in earthquake region, caused numerous cracks, landslide, seepage, etc.
When reservoirs subjected to earthquake leads to many dangerous circumstances which severely endanger reservoirs safety.
