Point Load 2. Line Load 3. It explains that vertical stress increases with depth due to overlying soil layers and can be calculated from the unit weight of each soil layer. Soil stresses are caused by overburden pressure from soil layers above and any added loads on the surface. Strip Load 4. It contains the following key points: 1. For non-elastic soils, the equation can be used if stresses are small compared to soil strength. 1 Stress in soil is caused by the first or both of the following :- (a) Self weight of Soil. Triangular Load 5. Stresses increase with depth due to self-weight and decrease radially from applied surface loads. Rectangular Load Added Stresses (Point, line, strip, triangular, circular, rectangular) Stress Distribution in Soils LECTURE 21 : VERTICAL STRESS DISTRIBUTION: Download: 22: Lecture 44: Compressibility and Settlement of Soil: Download To be verified; 45: Lecture 45 6 BOUSSINESCTS FORMULA FOR POINT LOADS A semi-infinite solid is the one bounded on one side by a horizontal surface, here the surface of the earth, and infinite in all the other directions The problem of determining stresses at any point P at a depth z as a result of a surface point load was solved by Boussinesq (1885) on the following assumptions. THEORY OF ELASTICITY. Boussinesq developed an equation to calculate stress distribution based on elastic theory. Factors that influence stress distribution include the size and shape of the loading area, load magnitude and type, soil type, depth, and distance from the Apr 5, 2017 · Stress distribution in soils can be caused by self-weight of soil layers and surface loads. These stresses are required for the stability analysis of soil mass, settlement analysis of foundations and the determination of earth pressures. STRESS DISTRIBUTION IN SOILS Importance of stresses in soil due to external loads. Boussinesq developed equations to determine stresses below concentrated, line, strip and rectangular loads by representing them as point loads and using Oct 31, 2020 · Several methods for estimating stress distribution are presented, including Boussinesq's method, Westergaard's method, and the use of influence factor charts and bulbs of pressure charts. Explore how stress distribution affects soil behavior under external loads. It also discusses stresses in saturated soils, distinguishing between total stress, pore water pressure, and effective stress. TOTAL NORMAL STRESS • Generated by the mass in the soil body, calculated by sum up the unit weight of all the material (soil solids + water) multiflied by soil thickness or depth. Boussinesq developed equations to determine stresses below concentrated, line, strip and rectangular loads by representing them as point loads and using Stresses in soil decrease with depth and distance from a loaded area. 1. To analyze soil compressibility and foundation capacity, the distribution of effective stress must be determined. (b) Structural loads, applied at or below the surface. Nov 22, 2016 · Stress distribution in soils can be caused by self-weight of soil layers and surface loads.
