Experimental research on navigation conditions in upstream channel of reconstructed lock at Hongjiang Hydro-junction
摘要
Abstract
The navigation safety issues in the upstream channel of the reconstructed lock at Hongjiang Hydro-junction were addressed.An in-depth investigation was conducted employing both fixed-bed physical model tests and remote-controlled self-navigating ship model experiments.The research revealed that the presence of winding shorelines in the reservoir area results in an S-shaped curve in the descending route,causing uneven force distribution between the bow and stern of vessels navigating the first bend.This leads to a tail-swaying and striking phenomenon,subsequently requiring vessels to quickly adjust their course for the next reverse bend,which not only complicates ship handling but also introduces significant navigational risks.To mitigate this issue,an effective improvement plan was devised through experimental optimization.By utilizing the anchorage on the opposite bank upstream and leveraging the gentle flow and depth characteristics of the reservoir area,the original consecutive S-shaped curved route was modified to a single curve.Meanwhile,the length of the upstream diversion dike of the existing lock remained unchanged.This enhancement not only successfully addressed the navigation safety concerns associated with the lock reconstruction but also serves as a valuable reference for similar projects.关键词
