TY - JOUR PY - 2008// TI - Earth pressure diagram and field measurement of an anchored retention wall on a cut slope JO - Landslides A1 - Song, Young-Suk A1 - Hong, Won-Pyo SP - 203 EP - 211 VL - 5 IS - 2 N2 - To utilize space more effectively for constructing apartments, roads, infrastructure, etc., excavation work is typically found in slope areas. An anchored retention wall has been installed because of the presence of soil slopes behind the walls and unsymmetrical excavation sections. An instrumentation system is normally applied on the anchored retention walls of slopes to observe and estimate lateral earth pressure acting on anchored walls. The earth pressure acting on the wall is decreased with increasing the deformation of the wall during the progress of excavation work. An earth pressure diagram acting on the anchored walls can be presented approximately as a trapezoid. The earth pressure at the ground surface is larger than zero. Also, the earth pressure is increased linearly from the ground surface to 15% of total excavation depth and then keeps constant. The earth pressure acting on the anchored retention walls installed on the cut slope is higher than that of the horizontal ground surface behind the wall, owing to the surcharge load of the slope soils.
