대형관입시험에 의한 N치와 강도정수의 상관관계

초록

Standard penetration test has some problems such as measurement of excessive N values although it is generally used in domestic subsurface exploration. Korea Institute of Construction Technology recently made KICT-type Large Penetration Test(LPT) equipment to solve these problems. In this paper, several times of SPT, LPT tests were performed in a large calibration chamber and triaxial tests of sand were carried out to suggest a function of relative density, friction angle, and LPT N value.
