It is a comprehensive engineering problem and related to the interaction of the soil and the supporting structure.
Engineering Description The excavation depth of the foundation pit for a twenty-three-layer frame structure is 6.7m.
Due to the distance is less than the excavation depth of the pit, the monitoring deformation of this engineering belongs to the first level.
In a word, the prestressed concrete supporting pile has certain engineering value and this paper can provides a reference to the design of the similar engineering.

It suggests engineering protective measures by summarizing the major determinant of excavation deformation.
Generally, mechanical properties of altered rock determine the stability and security of underground engineering.
The deformation of surrounding rock can not satisfy the engineering requirements.

Therefore, the supervision of the lightning has important civil and military meanings.
The lightning current model can be divided into the engineering model and the channel base current model, and the former reflects the currents in the whole lightning return stroke channel, and its base is the channel base current model which computes the current at any height point by the current of the channel base.
Heidler Model The lightning engineering model can be divided into two sorts , and the first sort of model thinks that the charge amount infusing in the lightning channel at certain time is decided by the earth, and the second sort of model thinks that the current value of the return channel base is decided by the charge amount infusing in the earth in the return, and the main engineering model usually used is the first sort.
The first early engineering model is the BG model, and this model thinks that the current at the any attitude point where the return waves are transferred up in the return channel equals to the current at the channel base ground, i.e. the current is transferred without losses and delays in the channel.
BG Model The first sort of engineering model usually used is the TL model, and this model thinks that the return current in the lightning transfers up along the return channel base without losses, and the transfer speed is constant, and the return channel is thought as an ideal transfer line.

The stepped soil-nail wall, as a new supporting method, was applied to practical engineering for improving the safety of the foundation pit which was supported by soil nailing.
In this paper, combined with the stepped soil-nail wall practical engineering, a numerical analysis model was established, and an overall analysis aimed at the deformation of foundation pit and soil nails internal force of the stepped soil-nail wall was performed.
