摘要
Abstract
Based on the uplift design of shearing method by current DL/T 5219-2005 regulations and the test data of the typical area with clay plus the gobi desert soil, the uplift limit state equation of transmission line undisturbed soil foundation were proposed, and the statistical parameters plus distribution of shearing method calculation variable were determined. Using“the first order second order method”, uplift design reliability level of undisturbed soil base were calibrated calculated, and the parameters sensitivity of partial factor, resistance variability plus calculation mode uncertainty were analysed. The results show that: For clayey soil, the undisturbed soil foundation uplift reliability index of shearing method by current regulation is about 3.89;For gobi desert soil, the calculated reliability index is higher. The above conclusions can be as references for DL/T5219 revision.关键词
