Determination of the Bearing Capacity of Soft and Polluted Silt Soils

연약한 실트지반과 오염된 실트지반의 지지력 결정

In this study, model tests of soft silt soils(ML) and silt soils was polluted with wastewater and waste oil from factories($ML_p$). Distribution of displacement, bearing capacity comparing the test results with existing theoretical expressions and analyzing the test results, the following conclusions were obtained. It was found out that in soft silt soils the relationship of critical surcharge and undrained cohesion is $q_{cr}=4.14C_u$ and polluted silt soils $ML_p$ those are $q_{cr}=1.78C_u$, respectively and the relationship of ultimate capacities $q_{ult}=9.53C_u$ and undrained cohesion in polluted silt soils are $q_{ult}=4.39C_u$. Critical surcharge and ultimate capacity is less in polluted silt soils than in soft silt soils.
