✅ Terzaghi, Hansen, Vesic, and Meyerhof’s methods are foundational approaches in geotechnical engineering for determining the bearing capacity of soils. Terzaghi’s method is the earliest and simplest, providing a basic formula for bearing capacity using three key factors. Hansen expanded on Terzaghi’s work by introducing additional correction factors to account for shape, depth, and load inclination. Vesic’s method further refined these calculations by incorporating plasticity theory and offering more accurate predictions for complex conditions. Meyerhof introduced a generalized bearing capacity formula that considered the influence of the shape of the foundation, the depth of the foundation, the inclination of the load.
Terzaghi‘s Method:

✅ Meyerhof’s method is a widely recognized approach for determining the bearing capacity of shallow foundations in geotechnical engineering. This method takes into account various factors that influence the bearing capacity, such as the shape of the foundation, the depth of the foundation, the inclination of the load, and the properties of the soil. Meyerhof’s approach is distinguished by its comprehensive consideration of these factors, leading to a more accurate estimation of the ultimate bearing capacity.

✅ Foundation Engineering: Bearing Capacity: Foundation engineering is a vital discipline within civil engineering that focuses on the design and construction of foundations for various structures. A key element in this field is the bearing capacity of the soil, which refers to the soil’s ability to support the loads imposed by the structure. Assessing bearing capacity is essential to ensure the foundation remains stable and secure, thereby preventing excessive settlement or structural failure. This process involves determining the maximum load per unit area that the soil can withstand without experiencing shear failure. Factors influencing bearing capacity include soil type, moisture content, density, and the dimensions of the foundation. Thorough evaluation and enhancement of bearing capacity are crucial for the durability and stability of any construction project.
✅ In this educational and concept-focused video, you will see: 1) Calculating the Ultimate and Allowable Bearing Capacity of Strip, Square, and Circular Foundations Using Terzaghi’s Method 2) Considering the Variation of Ultimate Bearing Capacity Values with Different Soil-Foundation Parameters such as Foundation Depth, Foundation Width, Soil Cohesion, Soil Internal Friction Angle, and Soil Unit Weight 3) Considering Special Cases in the Calculation of Bearing Capacity, Such As:
Non-Cohesive Soils (c’=0)
Zero Foundation Depth (Df =0)
Un-drained Soil Conditions (phi’=0)
Combonation1: (c’=0 & Df = 0)
Combonation2: (Df = 0 & phi’ = 0)
✅ Definitions: For the Strip Foundations : B = The width of the foundation For the Square Foundations : B = The dimension of each side of the foundation For the Circle Foundations : B = The diameter of the foundation Foundation Depth: Df = The depth of foundation measured from the ground surface gamma = Unit Weight of Soil c’ = Soil Cohesion or cu = Undrained Cohesion (phi =0) phi’ = Angle of friction of soil Sc , Sq & Sg : Shape Factors FS = Factor of Safety q = Surcharge: The soil above the bottom of the foundation can also be considered as being replaced by an equivalent surcharge (q= gamma . Df) Nc = The bearing capacity factor related to the contribution of soil cohesion Nq = The bearing capacity factor related to the contribution of surcharge N(gamma) = The bearing capacity factor related to the contribution of unit weight qu = Ultimate Bearing Capacity q(all) = Allowable Bearing Capacity

✅ Discover the fundamentals of weight-volume relationships in soil mechanics. Learn how to calculate and interpret soil unit weight, porosity, void ratio, and moisture content, and other volume-weight parameters. ✅ Understanding the relationships between different phases of soil is essential in geotechnical engineering and soil science. These relationships define how the solid particles, water, and air within soil interact and exist together. Soil is composed of these three phases, and the proportion and interaction of each phase affect soil properties like density, porosity, and moisture content. By studying these phase relationships, engineers can better predict soil behavior under various conditions, aiding in the design and construction of stable and safe structures. Join us as we delve into the basics of soil phase relationships and their practical applications in engineering.
