摘　　要：为保障浮式系船柱的系缆安全,依托京杭大运河某代表性船闸,针对其浮式系船柱的实际结构特点,根据数学力学基本原理推导构建了可反映浮式系船柱柱身应变信号与船舶系缆力二者之间定量关系的表达式。在此基础上,提出一套针对船闸浮式系船柱系缆安全的监测方法。为了验证该安全监测方法的可靠性,对依托船闸中的代表性浮式系船柱开展了现场试验。通过将安全监测方法所获得的船舶系缆力与传统载荷量测手段测得的系缆力值进行对比,发现二者的相对误差低于15%,表明提出的船闸浮式系船柱系缆安全监测方法具有较高的测量精度。To ensure the mooring safety of floating bollards in service,based on a representative ship lock of the Beijing-Hangzhou Grand Canal,according to the actual structural characteristics of floating bollards and the basic principles of mathematical mechanics,this paper deduces and constructs an expression that can reflect the quantitative relationship between the strain signal of floating bollards and the mooring force of ships.On this basis,a set of monitoring methods for the safety of mooring lines of floating bollards of ship locks are proposed.To verify the reliability of the safety monitoring method,field test is carried out on the representative floating bollards in the ship lock.By comparing the ship mooring force obtained by the safety monitoring method in this paper with the mooring force measured by the traditional load measurement method,it is found that the relative error between the two is less than 15%,which indicates that the safety monitoring method of the ship lock floating bollard mooring line proposed in this paper has high measurement accuracy.
