STRESSES IN SOIL Civil Engineering (强调在土壤中土木工程)
STRESSES IN SOIL Stresses at a point in a soil layer are caused by: 1‐Self weight of the soil layers (Geostatic Stresses) 2‐Added load (Such as buildings, bridges, dams, ettc.)) Stresses at a point in a soil mass are divided into two main typypes: I‐Geostatic Stresses ‐‐‐‐‐‐Due to the self weight of the soil mass. II‐Excess Stresses ‐‐‐‐‐‐From structures 1 By: Kamal Tawfiq, Ph.D., P.E.By: Kamal Tawfiq, Ph.D., P.E. Distributed Loads • Strip Loads (L/B 9) – Wall Footings – Embbankkements • Circular Loads (R) – Storage Tanks • Rectangular Loads (BxL) – Spread Footings – Mat Foundations 2 I. Geostatic stresses I.A. Vertical Stress Vertical geostatic stresses increase with depth, There are 3 types of geostatic stresses: a. Total Stress, σtotal b. Effective Stress, σ c. Pore Water Pressure,, u Total Stress = Effective stress + Pore Water Pressure σ = σ + u total I.B. Horizontal Stress or Lateral Stress σ = K σ h o v Ko = Lateral Earth Pressure Coefficient • For normally consolidated soils: KK == 11‐SinSinφφ’ o • For over consolidated soils: K = (1‐Sinφ’)(OCR)Sinφ’ o 3 II. Stress Distribution in Soil Mass: WhWhen appllyiing a lloadd on a hhalflf space medidium the excess stresses in the soil will decrease with depth. Like in the geostatic stresses, there ar
