Reliability Analysis of Non-Uniform Settlement of Foundation

Foundation soil was regarded as a random field, and a probabilistic model of the non-uniform settlement of foundation was established. Mean and coefficient of variation of non-uniform settlement of foundation were determined by first-order second-moment technique. Reliability analysis was then performed to compute the reliability index. As an example, the model was used for the calculation of the non-uniform settlement of a building. Values from calculation and measurment were compared and valuable conclusions were drawn.
