Abstract

The area of jointed-development plans in the Taichung green line rapid
transit is a highly urbanized with limited development space. The semi-circular
pile was adopted to increase the underground space as a retaining facility,
this method with higher technical and precision construction. By halving the
section of the pile, it could increase the space of the basement and reducing
carbon emissions.
With sharing this study, we hope the construction safety and engineering
technology in gravel formation could improve and better.
