| 摘 要： | 应用伯努利定理计算得到了理想状态的动水压力理论值，并进行了实际测量．测量结果证实了动水压力的存在，回归分析得到了实测动水压力与行车速度的平方呈正比的关系式．有压条件下渗透性试验结果表明，沥青混凝土在动水压力下的渗透性将急剧增大，对路面的危害严重．

| Abstract: | The dynamic hydraulic pressure(DHP) is calculated with Daniel Bernouli principle.The investigation verifies the existence of the DHP.A regression analysis reveals the relationship between the DHP and vehicles' traveling speed,namely,DHP is in proportion to the squared traveling speed.The test research on the permeability of the asphalt show that the permeability increases dramatically with DHP,which may damage the pavement seriously. |
