结合三峡船闸设计研究工作 ,通过分析闸墙施工过程中自重荷载、温度荷载以及完建运行时温度应力、渗透压力的作用 ,详细研究了锚杆取不同自由长度时锚杆的应力情况 。

The length of this special part of anchor rod is called the anchorage free length.

结合三峡船闸衬砌式闸墙的设计研究工作，提出了采用具有自由长度的锚固新方案。

The unconstrained length of externally prestressed tendon shall be determined in reason,and it shall not be over 12meters,then the frequency of concrete beam is not close to the one of the externally prestressed tendon,so the problem of sympathetic vibration can be avoided effectively.

体外索的无侧向支承的自由长度不应过大,根据常见桥梁频率和我国钢绞线的使用情况,体外索可控制在12m 之内,这样桥梁和体外索的自振频率就相互错开,也就避免了共振问题。
