Abstract

A coastal railway has a risk that traffic hindrance occurs for high waves. Storm waves were reproduced in hydraulic model tests. Wave overtopping characteristics were examined by 1/40 model tests in a wave channel. The pattern of ballast movement with different wave conditions was analyzed by 1/4 model tests in a channel. Based on the test results, the calculation formula for spray of wave overtopping was proposed, and the effect of wave splash barrier on ballast damage was also clarified.
