鉴于秦皇岛港工程开发的需要，本大根据该港多年实测潮汐资料，推算了该港的设计水位和校核水位。

For the need of the development of the Qinhuangdao port, based on the observed tidal data of many years at the port, the design water level and the check water level are calculated in this paper.

为了提高天文潮推算的精度，必须采用最接近推算年份的调和常数进行潮汐推算。

In order to improve the tide prediction, it is necessary to use new tide constants obtained from the nearest tide data.
