A Study on Soil Properties by Cone Penetration Test in Ulsan Samsan Area
Abstract
본 논문에는 피에조콘관입시험을 이용하여 울산 삼산지역 흙의 특성과 거동을 평가하였고, 또한 피에조콘관입시험의 결과들을 불교란 시료를 채취하여 행한 실내 시험결과들과 비교하였다.

울산 삼산지역의 흙은 유기물을 다량 함유하고 있으며 소성이 작은 점토로 나타났다. 과압밀비(O.C.R, overconslidation ration)는 약 1 또는 1 보다 작은 값으로 나타났으며 삼산지역의 흙은 정규압밀토 또는 미압밀토인 것으로 밝혀졌다. 또한 피에조콘관입시험과 표준관입시험 사이의 관계는 Kulhaway & Mayne 이 제안한 경험공식과 도표가 적합한 것으로 나타났다. 간극수압소산시험에 의하여 구해진 수평압밀계수와 Kh/Kv는 각각 1.0 ~ 6.24 ×10-³㎠/sec dhk 1.8 ~ 2.58 이었다.
In this paper, the properties of Samsan soil in Ulsan were evaluated by the piezocone test. The results of the piezocone test were compared with the laboratory test results of the undisturbed sample.

Samsan soil that contains various kind of organic was found out the low plastic clay. The overconsolitaion ratio (O.C.R) was carried out about 1 or less than 1. Hence it is provided that the soil is the normally consolidated clay or under consolidated clay. In addition, The correlations between the piezocone test and the standard penetration test were conformed to the charts and the empirical formulas by Kulhaway & Mayne. The coefficient of consolidation in horixontal direction and Kh/Kv were estimated at 1.0~6.24 ×10-³㎠/sec and 1.8~2.58 by the pore pressure dissipation test, respectively.

Conclusively, it can be evaluated out the properties of Samsan soil by piezocone test and suggested several values of empirical parameters.
