本文通过室内试验，研究了均匀坡底安装的小直径圆形墩在波浪、底坡、墩安装水深等不同条件下随机波浪的上升高度。本研究的主要目的是提出一个墩墩上2%的超额倾斜度的预测公式。公式用指数函数表示。预测值与观测值的相关系数为0.98。由于发现最大和三分之一最大起跑高度与2%的超额起跑高度呈线性相关，因此通过预测公式对其进行估计。利用该预测公式，还可以估计出桥墩最大倾斜度处的水深。
This study investigates runup heights of random waves on a small diameter circular pier installed on a uniform slope bottom, by laboratory experiments under various conditions of waves, bottom slopes, and installed water depths of the pier. The main purpose of the study is to propose a prediction formula for the 2% excess runup height on a pier. The formula is expressed by the exponential function. The correlation coefficient between the predictions and observations is 0.98. Since the maximum and one-third maximum runup heights are found to be related linearly to the 2% excess runup height, those are estimated through the prediction formula. By employing the prediction formula, one can also estimate the water depth where the runup on a pier becomes maximum.
