Abstract

In this research, by using the long water channel, the authors created solitary wave and analyzed the wave force applying on abutment-girder model (both girder and abutment are made as model). As a result, it is found that the horizontal force on abutment can be evaluated by the wave pressures on the front surface area of abutment. Besides, it is also noted that the wave pressures on the front surface area of abutment is about half of that on vertical wall structure, because the solitary wave could pass through the abutment-girder model between the two abutments, which led to the rise of wave height at the front surface of abutment became smaller compared with that at the front surface of vertical wall structure.
