.： 脱落，破碎；脱落, 破碎.According to the traffic situation at present in da-qin railway, part of its existing slab culvers can not meet the total needs of overloading,long-term operation will make the slabs of the culvert structure damage aggravate even fatigue damage, it will affect safety of train operation.
In order to make the theoretical model, accord with the objective reality of basic variable equivalent normal, so that in the reliability index reflects the β with reasonable distribution types of influence.And the limit state function in extended to more than two variables of more general nonlinear, through Z = 0 made a point of linear approximation, to avoid the center points error, this method called method of the test point, also is "unified standards", international "structure safety joint committee" recommended approach, abbreviation JC method.

Introduction Urban rail transit plays an important role to ease traffic pressure on big cities and promote the healthy development of urban economy and society.
In the meantime, urban rail transport also attracts more urban trips with its fast, convenient, efficiency and safety features.
The results showed that age, occupation, family income, T-costs, travel purpose, travel distance, and travel time have a significant impact on rail traffic travel behavior.

The establishment of warehouse model The optimization of warehouse transportation route will be affected by the right roadside rights and transport time, transport conditions (such as traffic flow and transport distance), road conditions (such as the type of road, road class, traffic capacity, etc.), transport costs (freight, fuel consumption, material distribution consumption), and many other limiting factors.
Under the premise of ensuring safety for the transportation of the warehouse, we always hope the shortest transportation distance, the least vehicle number and shipping most goods.
