摘要
用预应力法修复桥式起重机主梁下挠，近年来得到了较为普遍的应用。它具有修复周期短、工艺简单、操作方便，成本低等优点。现对该法的基本原理、构造要点、施工工艺、主要计算等作一介绍。
Using the inherent preload stress to repair the deflection of bridge crane beam has been applied more andmore in recent years. It has many advantages: simple technology, easy to operate, low cost and so on. Now the way is introduced about primary theory, construction, operation procedure, main calculation and so on.
