Abstract

Laboratory model test results for the ultimate bearing capacity of a surface strip foundation supported by a near-saturated clayey soil reinforced with layers of geogrid have been presented. The optimum values for the width of the reinforcement layers, the depth of reinforcement, and the location of the first layer of geogrid for mobilization of maximum bearing capacity have been determined. Based on the model test results, an empirical procedure to estimate the ultimate bearing capacity has been developed.

여러층의 지오그리드로 보강된 포화된 점토질지반에 띠기초의 극한 지지력에 대한 실내모형 실험결과를 제시하였다. 최대 극한지지력을 유발하는데 필요한 최적 보강길이와 보강심도, 첫번 째층의 지오그리드 보강심도를 도출하였다. 모형실험결과를 바탕으로 극한 지지력을 도출할 수 있는 준경험 방정식을 제시하였다.
