| 摘 要： | 浮桥进行投锚固定时,锚纲放出长度依据经验获得,使得投锚长度出现过长或过短现象,给浮桥的架设和使用安全产生危害。针对上述问题,根据悬链线理论对锚纲进行受力分析,将锚纲长度分解为悬链长度和卧链长度,进而得到一种计算锚纲长度的方法,并对其进行了安全性评估。

| Abstract: | When the floating bridge is anchored by anchors,the releasing length of anchor cable is always based on experience,which will bring troubles to security of anchoring because it is too long or too short.Aiming at the problem,based on the catenary theory,the paper conducts a force analysis of anchor cable,and divides the length of anchor into the length of hanging chain length and lying chain length.A calculating method is obtained,and its security evaluation is conducted. |
