최근 지구 온난화로 인한 이상 기후로 인해 과거보다 더 많은 지반공학 재해들이 발생하고 있으며, 재해들의 규모도 더욱 증대되고 있다. 최근 토목 및 건설분야에 소개된 바이오폴리머 기반 흙 처리(BPST; Biopolymer-based soil treatment) 기술은 효율적으로 흙의 강도를 증진시키면서 탄소배출이 거의 없는 친환경 지반보강법으로 알려져 있다. 특히, 아가검, 젤란검, 잔탄검과 같은 열적젤화 특성을 지닌 바이오폴리머들의 강도 증진 효과가 매우 우수함이 여러 연구를 통해 밝혀지고 있다. 하지만 바이오폴리머 함량 외에는 바이오폴리머 기반 흙 처리에서 흙의 강도 증진을 제어하는 주요 영향인자 규명에 대한 연구는 많이 부족한 실정이다. 본 연구에서는 기존 발표된 열적젤화 바이오 폴리머 처리 흙의 불구속일축압축강도(UCS; Unconfined compressive strength) 자료에 대한 기계학습 기반 선형회귀 분석을 통해 젤란검 바이오폴리머로 처리된 흙의 강도 발현을 결정하는 주요 인자들을 분석하였다. 해석 결과, 바이오폴리머 함량과 더불어 흙 속 점토 함량이 강도 발현에 가장 중요한 인자임을 확인할 수 있었다.

Abstract ▼ AI-Helper

Global warming caused by greenhouse gas emissions has rapidly increased abnormal climate events and geotechnical engineering hazards in terms of their size and frequency accordingly. Biopolymer-based soil treatment (BPST) in geotechnical engineering has been implemented in recent years as an alternative to reducing carbon footprint. Furthermore, thermo-gelating biopolymers, including agar gum, gellan gum, and xanthan gum, are known to strengthen soils noticeably. However, an explicitly detailed evaluation of the correlation between the factors, that have a significant influence on the strengthening behavior of BPST, has not been explored yet. In this study, machine learning regression analysis was performed using the UCS (unconfined compressive strength) data for BPST tested in the laboratory to evaluate the factors influencing the strengthening behavior of gellan gum-treated soil mixtures. General linear regression, Ridge, and Lasso were used as linear regression methods; the key factors influencing the behavior of BPST were determined by RMSE (root mean squared error) and regression coefficient values. The results of the analysis showed that the concentration of biopolymer and the content of clay have the most significant influence on the strength of BPST.
