Abstract
This paper firstly introduces the development of Monte-Carlo method in connectivity reliability and its advantages and disadvantages in the study of road connectivity reliability. Secondly, introduce the traditional Monte Carlo method to calculate the reliability of the connection, and improve the accuracy and speed of the traditional Monte Carlo method, that is, replace the pseudo-random number with Sobol sequence, which overcomes the The shortcomings make the result more accurate and increase the calculation speed from the side. Finally, by comparing the results of the Monte Carlo method and Monte Carlo method for calculating the reliability of road connectivity, the advantages of the improved Monte Carlo method in this respect are obtained. It shows that this method has certain correctness and superiority, and has a positive reference value for the evaluation of the reliability of the road connectivity. The research on the reliability of road connectivity, this paper improves the accuracy and speed of the traditional Monte Carlo method, that is, replacing the pseudo-random numbers with Sobol sequences, which overcomes the shortcomings caused by pseudo-random sequence sampling and makes the results It is more accurate and speeds up calculations from the side. Finally, by comparing the results of improved Monte Carlo method and Monte Carlo method for the seismic reliability calculation of roads, the advantages of improved Monte Carlo method in this respect are obtained. It shows that the method has certain correctness and superiority, and has a positive reference value for road reliability assessment.
