Abdul Hakam has carried out extensive research in the broad field of geotechnics, with a particular emphasis on soil mechanics and foundation engineering. His body of work spans both static and dynamic conditions, providing a comprehensive contribution to the understanding of soil behavior and its implications for civil infrastructure. Under static conditions, his research has focused on the performance of foundations in soft soils, which often present challenges in terms of settlement and bearing capacity. He has also investigated slope failure mechanisms, offering insights into preventive measures and stabilization techniques that are vital for infrastructure development in areas with weak or unstable ground. In the domain of dynamic conditions, Abdul Hakam has devoted significant attention to the stability of slopes and retaining walls under seismic loading, an issue of critical importance in earthquake-prone regions. His studies extend further into the phenomenon of soil liquefaction, where he has contributed to mapping areas vulnerable to this hazard. This research plays an essential role in disaster risk reduction and the development of safer construction practices. Beyond academic research, Abdul Hakam has been actively engaged in practical geotechnical projects. His involvement includes the design and construction of building foundations, assessment of road stability, and applied studies related to geohazards. The outcomes of his work have been disseminated through books, peer-reviewed journals, and international conference proceedings, thereby enriching both theoretical knowledge and engineering practice. Overall, his research reflects a strong integration of scientific inquiry and practical application, with a consistent focus on advancing geotechnical engineering for safer and more resilient infrastructure.
