Abstract

Two instrumented full scale tieback walls in sand were constructed at to Geotechnical Experimentation Site located on the Texas A 51M University Riversic Measurements were obtained from the one row anchor wall and from the two row at different times during construction. The measured performance of the tieback walls is presented and investigated. The these walls at different construction stage is evaluated with respect to lateral wall. settlement of the ground, bending moment of the wall. axial load distribution and anchor load variation. The fundamental mechanism of a tieback wall in sand is and explained with the measurements.

사질토 지반에서 앵커로 지지된 토류벽의 거동을 연구하기 위하여 텍사스 에이엔엠 대학에 소재한 미국 국립 토질 시험장에 계측기가 장착된 실물 크기의 앵커 토류벽을 시공하였다. 기간 중의 단계별 계측과 시공후의 계측을 실시하여 사질토 지반에서의 앵커 토류벽의 현장 거동을 분석하였다. 시공 단계별 토류벽의 수평 변천, 토류벽의 휨 모멘트, 토류벽의 연직 하중, 배면토의 침하와 앵커 하중을 계측하여 앵커 토류벽의 현장 거동을 분석하여 제시하였다. 사질토 지반에서의 토류벽의 거동 특성을 실측결과와 비교하여 분석하였다.
