| 摘 要： | 本文针对钢筋混凝土方沟侧壁开大洞口时的加固问题进行了分析，提出了一种“等代平面框架法”，用于侧壁开大洞口时方沟全断面的加固。通过一个典型实例的标准断面和等代平面框架内力计算结果的对比，对该方法进行了初步讨论，并提出了一些建议，可供参考。

| Abstract: | In this paper, the strengthening problem of reinforced concrete rectangular pipe with a large opening in its sidewall is analysed and an equivalent planar frame method is presented to try to solve this problem. A typical example, compared with the analytical results of a typical cross section, is given to check this method. Some suggestions are also given for reference. |
