| 摘 要： | 随着三峡枢纽的建成运行,重庆地区码头作业水文条件的改变以及船舶的大型化对斜坡式码头趸船系留设施提出了更高的要求。为确保港口安全生产,消除趸船现有系留设施存在的安全隐患,提出了一种考虑锚链和缆绳的弹性、悬链线的几何特征以及躺底段和贴岸段影响的多根不同方向锚链和缆绳共同作用的斜坡式码头趸船系留设施受力计算方法。结合工程实例,运用Matlab编程计算,计算结果符合经验规律,并与Optimoor软件计算结果吻合,验证了该方法的实用性和可靠性。

| Abstract: | With the completion and run of the Three Gorges Project, the change of hydrological conditions
for wharf operation and enlargement of ships in Chongqing put forward higher requirements to mooring facilities
attached to the pontoon for the sloping wharf. In order to ensure the safety of the port and eliminate security risks of
existing mooring facilities attached to the pontoon, we propose a calculation method for the force on mooring facilities
attached to the pontoon for the sloping wharf considering the elasticity and geometric characteristics of catenary for
the anchor chain and rope, the impact of the part lying in the river bed or bank slope and multiple anchor chains and
ropes working together in different directions. Programming calculation based on the practical project using Matlab
proves that the calculation result is in accord with the empirical rules and Optimoor, thus it verifies the practicality
and reliability of the method. |
