The gradual acceleration of the urbanization construction process makes civil engineering construction increase continuously, and soft soil foundation phenomenon is more and more common simultaneously. If the foundation soil is soft soil, the bearing capacity and the shearing resistance of the foundation soil are weak, particularly when the foundation soil is vibrated or loaded greatly, the strength of the foundation is obviously reduced and is in a flowing state, and then the local or overall shearing damage of the foundation is caused to form foundation settlement. The foundation settlement refers to the settlement of the foundation surface caused by the compaction of a foundation soil layer under the action of additional stress, and the inclination and the cracking of a building can be caused by the excessive settlement, particularly the uneven settlement so as to prevent the normal use.

At present, with the rapid development of urban motor train units in China, the application and maintenance of the urban motor train units become more and more important. The problem of foundation settlement is very prominent in areas with abundant rainfall and frequent typhoon disasters, so that the motor train unit in the urban area can not be normally used in the maintenance warehouse. The common anti-settling facilities comprise compensation structures which are mainly divided into two categories, wherein one category is to compensate by adopting a spring, and the other category is to compensate by adopting a hydraulic press.

In summary, the existing maintenance warehouse for the application of the urban motor train unit built on the soft soil layer mainly has the following problems:

1) generally, most foundations have soft soil at the bottom or have the bottom close to an underground water layer, so that the foundations are prone to settlement, the use of the foundations is affected, further, the motor train units in the urban area built on the soft soil foundations cannot be normally used when the motor train units are used for checking the warehouses, and the safety is very low.

2) If the spring is adopted as a compensation structure for foundation settlement, the problems of fixed compensation distance, uneven compensation distance, easy damage of the structure and the like can be mainly faced.

3) If adopt the hydraulic press as the compensation structure that the ground subsides, mainly face several aspects problems such as compensation cost height, structure are too complicated, difficult installation and manufacturing.
