초록

본 연구에서는 계측자료를 토대로 장기침하량을 예측하는 방법 중 쌍곡선법(Hyperbolic Method), 호시노법(Hoshino Method), 아사오카법(Asaoka Method)을 이용하여 경남지역 3개 연약지반 현장의 계측 침하량을 분석하여 압밀도를 평가하였으며, 대상지역을 압밀 초기, 압밀 후기로 구분하여 각 구분에 따라 압밀도를 분석하여 계측기간에 따른 침하량 예측방법의 적용성을 연구 하였다. 그 결과는 압밀 초기에서는 쌍곡선법>아사오카법>호시노법 순으로 적용성이 높은 것으로 분석되었고, 압밀 후기에서 아사오카법>쌍곡선법>호시노법 순으로 적용성이 높은 것으로 분석되었다.

영어초록

In this study, the degrees of consolidation were evaluated by analyzing the long-term settlement measured at the 3 work sites with soft ground in Gyeongnam Area. The Hyperbolic, Hoshino and Asaoka method were used, which were focused on prediction of long-term settlement of land on the basis of field measurement data. And the applicability of the settlement prediction method according to the measurement periods was investigated by analyzing the degree of consolidation at the target areas after dividing the terms into early and latter parts. According to the results obtained at the early stage of consolidation, the Hyperbolic method appeared to be in the highest applicability level, which was followed by Asaoka and Hoshino method in the order of level. In the case of latter stage of consolidation, Asaoka method appeared to be in the highest applicability level, which was followed by and the Hyperbolic, Hoshino method in the order of level.
