Abstract

A boundary element method with a Lagrangian approach and B-spline technique is employed to investigate characteristics of solitary waves attacking on beach slopes. By comparing numerical solutions with available laboratory measurements, it is shown that the maximum run-up heights of the present model are more agreeable than those of the existing numerical model. Variations of run-up heights and velocity vectors for different slopes are also described. Characteristics of hydrodynamic pressure acting beach slopes are investigated in detail.

Lagrange 방법과 B-spline 기법을 이용한 경계요소법으로 경사면에 작용하는 고립파의 특성을 연구하였다. 최대 처오름높이는 실험자료와 비교한 결과, 기존의 경계요소법에 의한 결과에 비해 높은 정확도를 나타냈다. 또한, 벽면 경사각의 변화에 따른 최대 처오름높이와 속도벡터의 변화를 나타내었으며, 경사면에 작용하는 동수압의 특성을 조사하였다.
