It should use lower deficient superelevation when it can’t in the case of the best situation. 1 Introduction From the beginning of building railways, rail wear problem was emerged and frequently appears in different types of rail traffic [1].
These parameters all influence the wheel/rail wear and the comfortable and safety of the train.
It is say that the vehicle is more safety.

Introduction As the urban population has rapidly expanded, the problem are prominently, which is living space crowd, urban traffic congestion and environmental degradation etc.
Investigation on disease basic situation Due to the design structure of the secondary lining on this tunnel line is plain concrete, the secondary lining on most tunnels appear varying degrees cracks and chip off-falling diseases, there is a serious threat to the safety operation on metro.

This ratio is even greater in bridge engineering due to continuous degradation, ever increasing traffic intensities and general lack of financial resources for rehabilitations of bridges.
In addition to the traffic loads described above, the bridge is exposed to permanent actions including layers of the road pavement and self-weight of the structural model.

Relief 9. check valve 10. safety valve 11. electromagnetic ball valve 12. two double-acting piston-cylinder Fig.2 Schematic diagram of erecting system Functions of the unit are detailed below: Power unit:The active force unit is consisted of frequency motor 1 and internal gear pump 2 , to provide pressure oil source to the hydraulic cylinder.
Charge unit is consisted of asynchronous motor 3, dosing pump 4, one-way valve 6, accumulator 7 and relief 8 to ensure consistent main pump 2 suction port and the discharge port traffic.
Actuator protection unit: safety valve is used to prevent the hydraulic cylinder 10 and the connecting pipe generate overshoot internal pressure, to improve system reliability. electromagnetic ball valve 11 is mainly used to lock the two chambers of the vertical cylinder when the erecting arm need maintaining a setting position.
