Data and supporting files for “Visual and quantitative geometric reliability analysis for soil-improved foundations using static load tests”

The study evaluates the effects of soil improvement on foundation bearing performance and reliability using repeated static load–settlement tests.</p><p dir="ltr">Three representative soil-improvement cases are considered: (1) geogrid-reinforced and unreinforced shallow footings, (2) grouted and ungrouted bored piles, and (3) ordinary and protective silicate-shelled bored piles.

For each static load test, the load–settlement response is represented using a two-parameter power-law model. The fitted parameters are treated as random variables and analysed using normal marginal distributions, a normal copula dependence model, and the Nataf transformation.</p><p dir="ltr">The supporting files include the load–settlement data used in the analyses and the numerical information required to reproduce the regression, statistical characterization, geometric reliability contours, reliability indices, design points, and sensitivity analysis reported in the associated publication.
