  Grant-in-Aid for Scientific Research(C)  Principal Investigator  22K04306 

  Key research topics focused on developing innovative construction methods to enhance construction efficiency while minimizing environmental impact. Another significant area of study was the construction of robust seabed foundation structures, emphasizing optimal pile arrangements.
  Technological advancements aimed to achieve highly accurate visualization of soil-structure interactions during the penetration process of structures. A load test device was utilized to observe the penetration of a model structure into the ground. Research also explored a novel penetration method combining rotational motion and vibration force.
  Fundamental studies indicated that with appropriate rotation speed and vibration period, it becomes feasible to drive piles to greater depths without requiring substantial penetration force.

• Improvement of evaluation technology for geological column and geotechnical characterization by continuous sampling

  Grant-in-Aid for Scientific Research(B)  Co-Investigator  23K22855 

  Aiming to innovate geotechnical investigation technology for offshore wind power facilities, an economical "continuous sampling" technique was studied to collect long soil samples from the same hole as the sounding.
  A sampling and cone penetration test (S&CPT) was devised, combining the cone penetration test (CPT) and the Geo-Slicer. While modifying the sampler structure, four field experiments were conducted on land sandy and clayey soils. It became possible to collect continuous samples of several meters, and it was confirmed that the quality was roughly equivalent to quality class 3 of ISO 22475-1.
