在兩相同波高之孤立波對撞或孤立波撞擊直立壁面之反射，在往昔的研究中多注重於孤立波之表面行為變化，如最大溯升、殘留時間及位相偏移等。對於孤立波撞擊直立壁面時，壁面的受力及其分佈之研究甚少。本文以試驗方式探討孤立波撞擊光滑直立壁之受力行為及其特性變化，包含孤立波在撞擊直立壁時，直立壁前之底床波壓變化、直立壁上之最大壓力分佈，及直立壁上之瞬時受力分佈等。在固定水深及不同的相對波高H/h (入射波高對靜水深之比)之試驗條件下進行試驗，並在直立壁面上密集擺設波壓計，對孤立波撞擊直立壁之最大受力及其受力分佈與壁前之底床波壓等作一量化處理。
試驗結果發現相對波高(H/h)會影響底床波壓及直立壁面上之受力分佈。值得一提的是在較大相對波高(H/h>0.4)時，因受非線性效應與交互作用之影響，在壁面上之受力分佈會呈現不對稱之雙峰形狀，此為首次以試驗證明此物理現象。另外，本文輔以解2-D RANS及 紊流模式之數值模擬(COBRAS)結果進行比較，結果顯示數值模擬與試驗結果有相當一致的準確性。

In this paper we conducted hydraulic experiment to study the pressure distribution of solitary wave on a vertical wall. Under different normalized amplitude ratios (H/h, initial wave amplitude over constant water depth), we analyzed the maximum instantaneous force, pressure distribution and the bottom pressure due to solitary waves collide on a vertical wall, these results were compared with available numerical model and theoretical analytic which were quantitative agreement.
We used wave gauges and pressure sensors to conduct the experiment, especially on a vertical wall and the bottom in front of a vertical wall, we concentrated to set pressure sensors. In addition to, we compared with numerical model results (COBRAS) which solves the 2-D Reynolds Navier-Stokes (RANS) and non-linear turbulence closure model and show quantitative agreements.
It is interesting to note that at higher normalized amplitude (H/h>0.4), the bottom pressure in front of a vertical wall and the force distribution on a vertical wall appears asymmetry double peaks, which is first shown by experiment, and the maximum instantaneous force is proportional to the normalized amplitude ratio (H/h).
