【Abstract】 The main factors influencing ultimate bearing capacity of foundation determined by Hansen formula are regarded as random variables.Combined with a practical project,ultimate bearing capacity of foundation is simulated and calculated by Monte Carlo method.The reliability indexes on bearing capacity of foundation under many circumstances,corresponding to the safety level of the current deterministic design method,are calculated by JC method.Analysis of sensitivity of the main factors influencing reliability index is also carried out.更多还原
