摘　　要：轮式车辆在积水路面行驶时会发生水滑,从而给行驶安全造成危害,已为驾驶人员所共知。工程技术人员对此作了一些实验性工作,并得出实验公式。该公式虽体现了车轮胎压的影响,但对于另一个主要参数———水深的影响缺少合理的表述。本文结合实验公式并考虑到水深、胎压、车速等条件,应用动量转换原理和液流斜楔动压理论对此现象进行分析,得出理论公式,该公式对水滑现象作出比较合理的解释。When motor running on the pavement covered by a layer of water,the driver must be careful to avoid Hydvoplaning which would cause serious accidentThe engineers have done a lot of experiments to study this and achieved a formula based on experimentAlthough this formula has indicated the effect of tire pressure,it takes no consideration of the effects caused by water depthThis article analyze the Hydvoplaning through the experiment taking into account of water depth,tire pressure,motor speed and so on,making use of the theory of momentum and liquid wedge principle,educed the theoretical formulaeThe formula has explained the Hydvoplaning logically
