Angle of Internal Friction Angle of Shearing Resistance

Web20 Aug 2024 · In the 1–4 m section, the internal friction angle was 25–28.7°, and the soil cohesion was 2.7–9.0 kPa. In the 24–29 m section, the internal friction angle was 23.7–23.89° and the soil cohesion was 13–15 kPa. As the depth increased, the soil cohesion increased, while the friction angle tended to decrease. hornsea burton primary school website
