How to Determine Vertical Stress on Soil Mass? (Newmark’s Chart) | Soil Engineering

Newmark gave a construction to determine the vertical stress at any point below a footing of any shape. Newmark's influence chart is based on the concept of the Boussinesq theory for vertical stress below the center of a uniformly loaded circular area. Construction of Newmark's Influence Chart: When a uniformly loaded circular area of radius r1 is divided into 20 [...]

Theories for Determining Vertical Stress in Soil Mass

The following points highlight the main theories and methods used for determining vertical stress in soil mass. Also learn about the comparison of different methods for determination of vertical stress in soil mass. 1. Boussinesq Theory for Vertical Stress due to Concentrated Load: Boussinesq in 1885 gave a solution for stress distribution in a homogeneous and isotropic subgrade subjected to [...]

Vertical Stress in Soil Mass below Strip Footing | Soil Engineering

Strip footing is used to support walls or retaining walls where length is considerably more than the width. The load is considered per unit area per unit length, say 1 m. Thus, the units for load are kN/m2 in SI system. Vertical Stress below Center of Strip Footing: Consider a strip footing of width B subjected to a uniform pressure [...]

Vertical Stress in Soil Mass

The vertical stress at any point in a soil mass due to self-weight of the soil may be considered under the follow­ing heads: 1. Total Stress 2. Pore Water Pressure 3. Effective Stress. 1. Total Stress: The total stress in a soil mass is the stress at any point due to the weight of the soil column above that point. [...]
