Reliability of the foundation needs to be calculated because of the uncertainty. Foundations are often used for critical structures, so reliability evaluation is an important aspect of design. Foundation design involves a lot of uncertainty, especially if there is not enough investigation in soil characterization and load testing. The analysis was carried out on the foundation of the High Speed Railway (HSR) Jakarta-Bandung bridge. The random variable used in the reliability calculation is the pile capacity where soil variability is taken into account. The load bias and resistance bias are also taken into account as random variables. In this study, the pile capacity was analyzed using the help of the SHAFT program. Calculation of pile capacity is carried out on piles that have load test data. The monte carlo simulation is used to calculate the reliability of the foundation. From the monte carlo simulation, the value of (safety index).
