CPT 결과를 이용한 말뚝지지력 예측법의 평가 및 신뢰성 분석 = Evaluation of CPT-based Pile Load Capacity Estimation and Reliability Analysis

국문 초록 (Abstract)

CPT는 1910년대에 처음 개발된 이후 지속적인 발전이 이루어져왔으며 지반특정 판별을 위하여 현재 가장 많이 시행되는 지반조사 방법 중의 하나이다. 본 연구에서는 신뢰성 높은 기초구조물의 설계를 도모하고자 CPT 결과를 이용한 말뚝의 지지력 추정법을 조사분석하였으며, 현장시험결과를 토대로 각 방법의 신뢰성을 평가하였다. 본 연구를 위하여 동일 지역에서 실시한 말뚝재하시험 결과 및 CPT 시험결과를 수집하여 말뚝종류에 따른 지지력 산정법을 비교분석하였다. 이를 위해, 수집된 재하시험결과에 대해 하중-침하량기준에 따른 측정지지력을 산정하고 이를 CPT 결과를 이용한 예측지지력과 비교함으로써 각 방법에 대한 상관도를 검토하였으며, 확률론적 방법을 이용한 신뢰성 분석을 통해 CPT에 대한 적용성을 검토하였다.

Since CPT was developed in 1910, it has been one of the most popular methods for geotechnical site characterization. In this study, estimation methods of pile bearing capacity using CPT results are investigated and analyzed for establish more effective and reliable foundation design system. Results of pile load tests and CPT, which were carried out in the same region, are collected and analyzed according to region and types of pile. Analyzing and comparing with loading test results, reliable CPT-based pile design methods for different load-settlement criteria are investigated. Based on pile load test and CPT results, reliability analysis for each method considered in this study also performed and adopted to evaluate reliability of methods for field application.
