滚装直跳板码头装卸作业潮位预报方法

针对滚装码头装卸车辆的潮位范围选择问题,以滚装直跳板为研究对象,分析跳板技术状态、船的状态、通行车辆性能和码头参数等因素对作业潮位的影响,并将影响情况定量转化为仅以跳板工作角度为未知数的不等式组,采用数值迭代法求解出跳板工作角度范围,进而预报作业潮位范围,并通过工程实例对该作业潮位预报方法进行验证。结果表明,该作业潮位预报方法具有普遍适用性,可用于指导滚装船制定码头装卸作业计划。

Forecasting method of tide level for loading and unloading operation on ro-ro wharf with straight type ramp

Aiming at the problem of choosing the tide level range of loading and unloading operation on ro-ro wharf,we take the straight type ramp as a research object,and analyze the influence on loading and unloading tide level of factors including ramp technical parameters,ship condition,vehicle traveling capacity and wharf parameters,and quantitatively convert the influence to a system of inequalities with ramp working angle as the only unknow,solve the system of inequalities by a numerical iteratively method,forecast the suitable tide level range,and verify the forecasting process by an engineering example.The results show that the method is applicable to the prediction of tide level,and it can be used to guide ro-ro ship to make the loading and unloading plan.
