The Effect of Vertical Load on the Monotonic Behavior of Hybrid Caissons under Combined VHM Loading.
The Effect of Vertical Load on the Monotonic Behavior of Hybrid Caissons under Combined VHM Loading.
In recent years, the development of offshore structures has significantly increased for the exploitation of renewable energy resources and the extraction of underground resources. Hybrid suction caissons comprising a skirted or mat foundation with suction caisson has been proposed as an innovative foundation for offshore structures especially offshore wind turbines (OWTs). One of the important factors affecting the performance of these types of caissons is the vertical load imposed on them which can have various effects on their behavior. So far, few studies have been conducted on the effect of vertical load on the behavior of hybrid suction caissons. In this study, a series of geotechnical centrifuge tests at 40g have been carried out to investigate the effect of vertical load on the behavior of hybrid suction caissons subjected to combined VHM monotonic loading. The results reveal that there is a specific limit for the vertical load to the vertical bearing capacity ratio which can enhance the ultimate bearing capacity of caissons under VHM loading.
