BRIN audits retaining wall structure technology in coastal areas
BRIN engineer Affandy Hamid said in a statement in Jakarta on Friday that the audit used structural mechanics modeling to compare two tie-rod designs: the patented diagonal (Type A) and BRIN’s horizontal alternative (Type B).
“This innovation is a promising alternative for sustainable coastal infrastructure development,” he said.
Hamid explained that the research demonstrated that PCP structures offer several advantages over conventional construction, including reduced concrete use, ease of construction, and greater space efficiency.
The structure also allows for the use of local fill materials, further supporting the concept of green infrastructure.
Furthermore, Shafan Abdul Aziz, another BRIN engineer, also assessed that PCP has great potential as a more efficient and environmentally friendly coastal protection solution while maintaining good structural stability.
“Simulation results show that PCP structures remain stable without the need for additional pile foundations as long as the foundation soil conditions meet certain requirements. This adds value in reducing construction costs and accelerating the development process,” he said.
Aziz explained that the research was motivated by the increasing risk of damage to coastal areas in Indonesia due to climate change, which is characterized by abrasion, tidal flooding, and land subsidence.
With a very long coastline, Indonesia requires infrastructure innovations that are not only strong but also sustainable, he said.
Going forward, the BRIN engineering team recommends further testing through physical experiments to validate the numerical modeling results, accompanied by a comprehensive study of the material’s long-term corrosion resistance.
