摘　　要：以某高校40 m跨度拱形大门为例,探讨了大跨度现浇钢筋混凝土拱形结构在结构布置、计算方法和基础选型等方面难点和处理技巧.提出可以通过设置横梁连接几个相对独立的拱圈,实现上部结构的稳定;通过调整独立基础底面的倾斜角,抵抗拱圈的水平推力;适当加大独立基础的重量,可提高整体稳定性.Taking a 40 m-span arch gate in university as an example, the structural layout, calculation method and foundation type of long-span cast-in-situ RC arch are discussed, corresponding treatment measures are also put forward. In order to guarantee the stability of the upper arches, the transverse beams are built to link the relatively independent arches. The foundation is slanted to equilibrate the horizontal thrust. To increase properly the weight of single foundation, the whole stability can be improved.
