An Introduction to Bearing Capacity Analysis

This publication will introduce you to methods for analysis of soils and rock to determine load bearing capacity. Stresses transmitted by a foundation to underlying soils must not cause bearing-capacity failure or excessive foundation settlement. The design bearing pressure equals the ultimate bearing capacity divided by a suitable factor of safety. The ultimate bearing capacity is the loading intensity that causes failure and lateral displacement of foundation materials and rapid settlement. The ultimate bearing capacity depends on the size and shape of the loaded area, the depth of the loaded area below the ground surface, groundwater conditions, the type and strength of foundation materials, and the manner in which the load is applied. Here is what is discussed: 1. BEARING CAPACITY OF SOILS, 2. SHEAR STRENGTH PARAMETERS, 3. METHODS OF ANALYSIS, 4. TENSION FORCES, 5. BEARING CAPACITY OF ROCK, 6. SELECTION OF FOUNDATION TYPE, 7.
