Reliability analysis of a concrete tunnel lining by the Monte Carlo integral approximation method with Duddeck’s predefined calculation Model

This paper presents the calculation of Reliability by using the Monte Carlo integral approximation method of probability density function. In case the basic variables are statistically independent and normal distribution with a predetermined calculation model by Duddeck. The analysis results of Reliability of concrete tunnel lining are made for the specific geological conditions of the Nhon - Hanoi railway project and the other numerical results are demonstrated in this article.
