abstract="In order to address uncertainties of geotechnical parameters and loads in pile foundation design, firstly, a RGD method considering multiple failure modes was proposed. Four typical failure modes, vertical ultimate limit state (ULS), vertical serviceability limit state (SLS), horizontal strength failure and horizontal deformation failure were analyzed. Then, Monte Carlo simulation (MCS) and point estimate method (PEM) nesting were adopted to compute mean value and standard deviation of failure probability for soil-pile foundation system, and the latter was used as an indicator to measure robustness. Finally, optimal design of soil-pile foundation system was finalized with robustness and cost as objectives. The results show that piles with different geometries have different dominant failure modes. With the increase of geometries, key failure mode changes from horizontal strength failure to vertical SLS, which has significant influence on gradient of of system' failure probability. © 2020 China Safety Science Journal.
