Properties of metro engineering construction determine it’s a high-risk construction project.
The security incidents happened in the metro engineering construction is often caused by poor supervision and inspection [1].
Combining the principal component analysis results with practical engineering, we classify and reorganize the 9 principal components.
The manifestations of the influencing factors will be different depending on the different engineering backgrounds.

Because the method of reconstruction at original position can meet the requirement of reconstructing Small Clear Spacing Tunnel primely, it’s highly favored in engineering.
Engineering Situation Yuzhou Tunnel is a portion of Widening and Reforming Project in Chongqing Airport Road.
Because of convenient and fast molding method, fast and accurate internal calculation module, and strong operability on post-processing, the software is favored by geotechnical engineering field.
