The characteristics of the transmission method are that it can be easily interfered at the ground or elevated section by the civil signals from the ground or elevated areas, and inside the monorail tunnel, its transmission performance is relatively stable thanks to a closed environment
The system design and test platform, software testing platform of the engineering stage.The simulator of the minimum system is separated from the constraints of the hardware environment, in the circumstances of combining with the existing simulation test platform function library and model library, it can rapidly implement the engineering design prototype, and validate the usability of the overall solution, it can find some latent risk in the early stage of the project, greatly improve usability of the overall solution.
As a signal system project, it shall achieve the safety requirements of the laws and regulations, but there is no mature signal engineering security authentication mechanism in China.
In the engineering application, adequate measures can be taken according to the actual situations to avoid interference to the effective transmission, so as to achieve better operational effect of the system.

Consideration on Group Excavation Engineering GUO Li-qun1,a, CHENG Yu-guo 1,b 1The College of Civil Engineering ,Huaqiao University,Quanzhou,China.
On the base of analysising the sections relevant group excavation engineering in Chinese codes, suggestions were given in the aspects of engineering investigation,design,construction and monitoring.
The precautions for group excavation engineering Group excavation engineering is a typical engineering problem the construction personnel are facing in the urban undergroud space development nowadays.
It is difficult to guide engineering investigation,design,construction, monitoring in group excavation engineering.
Engineering investigation.Engineering investigation provides necessary informations for the design and construction of excavation engineering. points for attention should be carried out in the investigation of group excavation engineering : (1) During the planning stage, if there will be a group excavation engineering in the project, the project environmental assessment should include the impact of group excavation on the environment

Applications of GIS-Enhanced Networks of Engineering Information Domenic Mario Sergi1,a and Jie Li1,b 1School of Civil, Environmental & Chemical Engineering, RMIT University, Melbourne, Australia adomenicsergi@gmail.com, bjie.li@rmit.edu.au Keywords: BIM, GIS, Cloud, Disaster, Retrofitting.
Analysis of the Design Process In order to fully understand the manner in which data will play a role in the engineering process, it is first necessary to examine exactly what engineering design is, and how it operates.
Therefore, in “drawing” the structure, the engineer is actually defining the dead loads.
Autodesk uses the BIM and GIS data as inputs into the relevant engineering standards to calculate design loads.
