摘要：

随着船闸水头提高,闸室尺度加大,阀门快速启闭,输水流量大,引航道的水力条件成为控制因素。因此,根据规范要求,采用计算分析、对比和论证的方法,根据船闸水头、尺度及运输条件,计算分析闸室与引航道停泊条件的差异,相同航道等级不同闸室尺度引航道停泊条件等。结果表明:随着船闸水头提高与闸室尺度的加大,应重视引航道的水力条件;引航道断面设计不只与船型尺度有关,应与输水流量联系起来;当引航道船舶(队)不满足停泊条件时,有一系列改善措施,可供选择应用。

Along with rising of water head of lock,increasing of lock chamber dimension,valve rapid opening and closing and increasing of water delivery volume,the hydraulic condition of lock approach has been the control factor.According to the requirement of code,a method including calculation,analysis,antitheses and demonstrate is adopted,the calculation and analysis of different anchorage conditions between lock chamber and approach channel is carried out as per lock water head,dimension and run conditions,and anchorage condition under the conditions of same channel classes and different lock chamber dimension.The results show that hydraulic condition of lock approach channel should be regarded when water head of lock and lock chamber dimension are increased.The approach channel section design is not only related to dimension of ship,but also water delivery volume.When approach channel is not met with anchorage conditions,a series of improved measures can be selected.
