초록

말뚝 해석 프로그램인 PAR에 의하여 말뚝의 극한 수직 및 수평 지지력을 예측할 수 있는 방법을 제안하였으며,현장에서 수행된 말뚝재하시험 결과들을 이용하여 PAR에 의한 사례연구를 수행하였다. PAR에 의해 해석된 말뚝의 극한지지력은 정재하시험에서 구한 지지력에 대하여 약 15%이내의 오차범위에 들었다. 또한, 강관말뚝들에 수행된 정재하시헙, 정.동재하시험 그리고 PDA 결과들을 비교하였으며, PAR에 의해 극한지지력을 예측하였다. PAR을 이용하면 말뚝의 축방향 하중의 분포를 예측할 수 있었으며, 여기서, 하중전이해석도 근사적으로 수행할 수 있었다.

A predicting method for ultimate vertical and horizontal bearing capacity by means of PAR(Pile Analysis Routines) was suggested. Based on the static pile load test data, case studies by means of PAR were performed. Ultimate pile capacity predicted by PAR was within 15% error range of that determined by stairs pile load tests. Also, the results of static pile load test, statnamic tests and PDA data performed on pipe piles were compared and, by using PAR, ultimate pile capacity was determined. Distributions of atrial pile load could be predicted and load transfer analysis could be done approximately by those distributions.
