Abstract

To design segment lining, loads such as self weight, vertical load, horizontal load, ground reaction, water pressure, backfill grouting pressure et al. have to be considered. Earth pressure and water pressure are the major factor to design segment lining such as concrete strength, segment thickness and amount of rebar et al. To analysis earth pressure and water pressure acting on segment lining, filed monitoring and back analysis are performed in this study.

세그먼트 라이닝 설계시 고려하는 하중은 자중, 연직하중, 수평하중, 지반반력, 수압, 뒤 채움 주입압, 부력 등이 있으며, 이 가운데 토압과 수압은 세그먼트 라이닝 설계시 콘크 리트 강도, 세그먼트 라이닝의 두께 및 철근량 등을 결정하는데 가장 큰 영향을 미치는 주요 인자이다.따라서 본 연구에서는 쉴드터널 시공단계별 계측결과를 토대로 세그먼트 라이닝에 발 생하는 휨모멘트 계산하였으며, 이를 역해석 결과와 비교분석을 통하여 세그먼트 라이 닝에 작용하는 토압 등을 분석하였다.
