- Abstract
Reliability analysis of uplift stability based on the first order second order method for digged foundation in gravel soil has been made by non-dimensionalization for ultimate state equation and combining with the test results. The ratio of test value to calculated uplift capacity Kp that reflects the uncertainty of calculation model obeys normal distribution via single sample K-S test. When the ratio ? of variable and permanent loads is certain, reliability index ? increases linearly with safety factor K. For given value of K, reliability index ? change slightly with ?. For digged foundations in gravel soils, the reliability index ? ranges from 2.74 to 3.22 when K=2.5- 4.0.
