Evaluation of Ground Improvement on Sands at Yongjong Island Geotechnical Experimental Site

영종도 지반공학 야외시험장에서의 사질토지반 개량효과 평가

In situ experimental studies were Performed at Yongjong Island Geotechnical Experimental Site to evaluate the ground densification on sand deposited. Standard penetration test, cone penetration test, and SASW test were performed and soil profiles and quality of ground improvements were evaluated. The feasibility of applying SASW method were verified by comparing test results. The evaluation technique of in-situ density using SASW and resonant column tests was proposed, and the reliability of proposed method was verified by performing case studies.
