Study on Application of Reliability Theory to Safety Evaluation of the Yellow River Dike

摘要

For evaluating the safety of a dike, it is essential to carry out the seepage and slope stability analysis. The results of seepage and slope stability analysis are much related to the geotechnical parameters. Due to the complex geological conditions and the great variability of soil parameters of the Yellow River dike, it is very hard to come up with actual results by deterministic methods. If reliability theory is applied for safety evaluation of the Yellow River dike, the variability of the parameters of soil properties can be fully considered. The results will well accord with the engineering practice. By analyzing the basic methods of reliability theory and studying the specific implementation methods for the safety evaluation of the Yellow River dike, it has proven that application of the method is much valuable and innovative.
