摘要： 通过分析现有拱形结构在异形平面条件下排布设计中存在的问题，综合考虑了跨度、拱座标高和伸出长度的影
响，提出了在立面以斜切圆柱面实现拱结构两端面跨度不等，在平面上以异形平面中心线为定位基准线，以拱座最小
伸出长度和标高为控制值，确定拱座与预制拱结构的分界线。然后以异形平面中心线为预制结构排布基准，使得预制
构件不仅中心位于平面中心线上，而且预制构件纵轴线垂直于平面中心线。新型排布方法不仅能解决复杂异形平面形
状条件下拱形结构两端跨度不等的难题，同时能够实现拱结构两端拱座的标高和伸出长度保持一致，实现社会效益和
经济效益皆优的有益效果。

Abstract: By analyzing the problems existing in the layout design of existing arch structures under the condition of irregular
planes, and taking into account the influence of span, arch pedestal elevation and extension length, it is proposed to
realize the unequal spans of the two end faces of arch structures on the facade by means of diagonally tangent cylindrical
surfaces, to determine the boundary between the arch pedestal and the prefabricated arch structure by taking the center
line of the irregular plane as the positioning reference line on the plane, and the minimum extension length and elevation
of the arch pedestal as the control values. Then take the center line of the special -
shaped plane as the layout datum of the
prefabricated structure, so that the center of the prefabricated component is not only located on the center line of the plane,
but also the longitudinal axis of the prefabricated component is perpendicular to the center line of the plane. The new layout
method can not only solve the problem of unequal spans at both ends of the arch structure under the condition of complex
irregular plane shape, but also achieve the same elevation and extension length of the arch pedestals at both ends of the
arch structure, achieving the beneficial effect of excellent social and economic benefits.

在无柱车站设计中，混凝土直梁一般适用于跨度小于
1 0 m 的 地铁车站；对于跨度超过20 m 的 车站而言，由于拱
形 结构容易实现较大跨度，结构受力合理，适合采用混凝
土 建造的优点，多采用拱形结构形式。同
