【摘要】：为探求斜坡堤典型胸墙迎浪面所受波浪力大小的影响因素,设计前仰式、深弧式、后仰式和直立式4种结构型式胸墙进行相关的物理模型试验。通过在典型胸墙迎浪面间隔布置压力测点,获取所受波浪压力,并将其进行积分求和,得到胸墙所受波浪力,进而讨论相对波高、相对波长、斜坡坡度和胸墙结构型式对波浪力的影响。结果表明,相对波高与相对波长对胸墙所受波浪力影响显著;波浪力随着相对波高的增大而增大,随着相对波长的增大呈现先增大、后减小、再增大的变化趋势;波浪力随着斜坡坡度的增大而减小。斜坡堤弧形胸墙所受波浪力明显大于直立式胸墙所受波浪力;在斜坡堤弧形胸墙中,前仰式胸墙受力较其余两种型式胸墙受力小。研究结果将加深波浪对斜坡堤胸墙作用力的理解,为后续工程设计提供理论指导。
[Abstract]:In order to find out the influence factors of the wave force on the typical chest wall of the slope embankment, four types of chest wall, namely, the front tilting type, the deep arc type, the backward type and the vertical type, are designed to carry out the related physical model tests. By arranging pressure measuring points at the interval between the wave face of typical chest wall, the wave pressure is obtained, and the wave force on the chest wall is obtained by integral summation, and then the relative wave height and the relative wavelength are discussed. The influence of slope and chest wall structure on wave force. The results show that the relative wave height and the relative wavelength have a significant effect on the wave force on the chest wall, and the wave force increases with the increase of the relative wave height, and increases first, then decreases and then increases with the increase of the relative wave length. The wave force decreases with the increase of slope. The wave force on the curved chest wall of the slope embankment is obviously greater than that on the vertical chest wall, and in the arc chest wall of the slope embankment, the force on the front and back chest wall is smaller than that on the other two types of chest wall. The results of the study will deepen the understanding of the wave force on the slope embankment chest wall and provide theoretical guidance for the subsequent engineering design.
