弯曲河段口门区船舶安全通航判别条件
|
摘要
为了研究弯曲河段的船舶安全航行条件,考虑引航道布置在凸(凹)岸、上(下)游引航道水流条件及船舶航行的特点,建立了弯道概化模型。通过水流条件试验和船舶模型航行试验,完善了弯曲河段船闸口门区船舶安全通航的判别公式,提出口门区船舶安全通航的2种判别方法。通过试验,验证了该方法的合理性。
In order to study the safe navigation conditions of ships in curved reach, a generalized model of curved channel is established, considering that the approach channel is arranged on convex and concave banks, the flow conditions of upstream and downstream approach channels, and the characteristics of ship navigation. The discriminant formula for safe navigation of ships in lock entrance area of curved reach is improved and two discriminant methods for safe navigation of ships in lock entrance area are put forward, through the flow condition test and the ship model navigation test. The rationality of this method is verified by tests.
