Abstract. From the very beginning of the soil mechanics the interest for understanding the role of the pore water pressure is evident. In fact, the role of pore water pressure has been investigated even earlier by the agronomic sciences, which prepared a strong base for by: 2. Matric suction is of more importance in the analysis of cohesionless soil, like sand, but has secondary effects in semi- cohesive soils. Although Fredlund [32] highlighted this increase in pore. The presence of soil suction is particularly important in the study of slopes where, should the porewater pressure increase, stability brought about by suctioninduced increases of strength can be compromised. Over the last 20 years, methods for measuring soil suctions in laboratories and on sites have been : Andrew Ridley.

The presence of soil suction is particularly important in the study of slopes where, should the porewater pressure increase, stability brought about by suction-induced increases of strength can be compromised. Over the last 20 years, methods for measuring soil suctions in laboratories and on sites have been : Andrew Ridley. The total suction pressure is the opposite (or negative) pressure applied by the external gas on the soil water resulting in a pool of pore water in equilibrium through a semipermeable membrane with the soil water (Krahn and Fredlund, ). Soils τ f = c + (σn-u w) tan φ =c + σ' tan φ where τ f is the shear strength, σis the normal stress, u w is the pore water pressure, φis the angle of friction and σ’ is the effective normal stress Effective normal stress σ’ is the stress carried by soil particles. For saturated soils, u w is Size: 2MB. The soil water characteristic curve (SWCC) defines the relationship between water content and soil suction. The chapter also discusses the methods of measuring soil suction and techniques that can be used to estimate soil most commonly used methods for measuring soil suction include (1) tensiometers.
