1.1 Definition and type of earth pressure Lateral earth pressure: Lateral earth pressure = K * over burden stress or, σh = K* σv or, σh = K* γZ where, K = Coefficient of lateral pressure Types of lateral earth pressure: 1. Earth pressure at rest 2. Active earth pressure 3. Passive earth pressure 1.2 … Read more

Water has the most significant effect on the behavior of soil. Gravitational water: Percolates through the soil under gravity Pore water pressure at GWT = 0 Soil above GWT is saturated by capillary action (pore water pressure is tensile and negative = -ϒwh) Above GWT – impervious formation above- local saturation Water occurring at local … Read more
