Abstract

There always exists uncertainty which is mainly due to uncertainty of the evaluation of a geotechnical structure at a site. The uncertainty in the geotechnical analysis can be considered in the probabilistic analysis using the Monte Carlo Simulation. It needs various soil profiles which could be possible at the target site. In this study, a new method is proposed to generate soil profiles which are probable at the site. The proposed method analyzes a structure of a site and generates one dimensional soil profiles for a probabilistic analysis. Through the field application, the applicability of the prosed method was shown.

지반 해석 결과에는 항상 불확실성이 존재하며, 이러한 불확실성은 주로 지반 구조의 불확실한 평가에 기인한다. 이러한 지반 구조의 불확실성에 따른 지반 해석 결과의 불확실성은 몬테카를로 시뮬레이션을 사용한 확률론적 해석에 의해 고려될 수 있다. 몬테카를로 시뮬레이션을 사용한 확률론적 지반 해석의 수행을 위해서는 대상 지반에서 존재 가능한 다양한 지반 구조의 생성이 필요하다. 본 연구에서는 확률론적 지반 해석을 위한 대상 지반에서 존재 가능한 다양한 지반 구조 생성 방법을 제안하였다. 제안된 방법은 대상 지반에서 획득된 지반 조사 결과를 바탕으로 하모닉 웨이브릿 변환을 사용하여 지반 구조를 평가한 후, 이로부터 대상 지반에 존재 가능한 다양한 지반 구조를 생성할 수 있다. 제안된 방법은 실제 현장 조사 결과들에 적용되었으며 이를 통해 제안된 방법의 현장 적용성을 확인할 수 있었다.
