| Abstract: | The reliability of the vertical bearing capacity of rock-socketed piles is analyzed using FORM and Monte-Carlo.Through an example,the influence of distribution function types and variable correlation on reliability index is analyzed.The relations between the reliability index and such factors as the variation coefficient,the rock-socketed depth,the diameter of piles,the live and dead load effect ratio as well as the safety factor are discussed.Some beneficial conclusions are reached. |
