In many construction sites, corrugated pipe is emerging as an effective alternative due to its outstanding constructability and economic feasibility compared to the precast concrete method. Corrugated pipe responds flexibly to external loads and is resilient against brittle fracture. However, during installation by the cut-and-cover method, it deforms along with the surrounding ground, which can cause ground surface heave or settlement. 

Numerical analysis is being performed to investigate how the various parameters affect the deformation behavior of corrugated pipe. Additionally, the optimal modeling method to examine the interaction between the corrugation and the backfill soil is also being studied.
