Abstract
It is very important to evaluate the geotechnical characteristics of marine soils, which supports the coastal/offshore structures, in the design and construction of the structures. Although the marine site investigation is much more difficult than onshore site investigation, unfortunately, safe and precise jobs have not been accomplished in Korea because of the insufficiency of the test equipments. Therefore, the development of the technologies for site investigation equipments is one of significant and necessary research jobs for the construction of a world-class ocean community in the near future. The main objective of this study is to develop a new type of marine cone penetration testing(CPT) system, which can be utilized to even deep sea and high depth of soil layer. The system is one of seabed types and employs the conventional cone, which shows more reliable results than miniature cone. The most important parts of the marine CPT, i.e., successive rod system and cone penetration system with wheel drive, were preliminarily developed in this year, and are scheduled to be verified with some filed tests at onshore in a near future. The final equipment developed after improvement and modification processes including insitu tests at offshore is expected to be applicable to various sites with practical/economical advantages. Furthermore, if the marine CPT equipment is successfully manufactured, our own competitive power in a world could be secured by adopting the core technologies on the equipment to the various other coastal/offshore site investigation tools.
