The invention provides a train speed calculation method, device and equipment and a readable storage medium, and the method comprises the steps: obtaining first information, second information and third information, the first information is the instantaneous speed when a first train passes through a current bridge pier, the second information is the ground vibration speed corresponding to the instantaneous speed at a first position, and the third information is the ground vibration speed corresponding to the instantaneous speed at a second position; the third information is ground vibration velocity corresponding to the instantaneous velocity at the second position; the first position and the second position are both arranged on a connecting line of the pier and the target, the shortest distance between the first position and the pier is a preset distance, and the second position is arranged between the first position and the target; establishing a vibration velocity attenuation model according to the first information, the second information and the third information, wherein the vibration velocity attenuation model is used for calculating the ground vibration velocity corresponding to the instantaneous velocity conducted to the target; according to the vibration velocity threshold value and the vibration velocity attenuation model, the maximum instantaneous speed of the second train passing through the pier is obtained. According to the method, the maximum speed allowed when the train passes through the target can be rapidly obtained through the vibration velocity attenuation model.

    本发明提供了一种列车速度计算方法、装置、设备及可读存储介质,所述方法包括获取第一信息、第二信息和第三信息,第一信息为第一列车经过当前桥墩时的瞬时速度,第二信息为第一位置处与瞬时速度对应的地面振速,第三信息为第二位置处与瞬时速度对应的地面振速;第一位置和第二位置均设置在桥墩与目标的连线上,第一位置与桥墩之间的最短距离为预设距离,第二位置设置在第一位置与目标之间;根据第一信息、第二信息和第三信息建立振速衰减模型,振速衰减模型用于计算瞬时速度传导到目标处对应的地面振速;根据振速阈值和振速衰减模型,得到第二列车经过桥墩的最大瞬时车速。本发明通过振速衰减模型可快速得到列车经过目标处时所允许的最大车速。
