Field Study on Earth Pressure of Finite Soil Considering Soil Displacement

The classical earth pressure theory assumes a semi-infinite soil behind the wall, which is no longer applicable to problem of in case finite soil. A field study was conducted investigate at different excavation depths. cells were used measure change along depth, and measured pressures compared with calculation results for Moreover, influence width-to-depth ratio, cohesion, internal friction angle on also analyzed based theoretical method. research show that Rankine active pressure, more suitable situation. difference under ratios would increase while cohesion had little effect
