【 摘 要 】

The characteristics of the reflection coefficients of a step-shaped slit caisson on the rubble mound are examined by experimental data.A numerical analysis which combines the method of matched asymptotic expansions with a boundary element method has been applied for the calculation of the reflection coefficients of the caisson on the rubble mound. Numerical results are compared with experimental data to show the validity. Dimensions of the preferable cross-section of the step-shaped slit caisson on the rubble mound are discussed and obtained through the numerical results.
