拱形结构通过连续的形态形成覆盖空间，同时提供灵活的活动区域。拱门作为一种常见的空间形式，也传达出开放和欢迎的氛围。

木构拱形结构可以由单个拱延展为连续的拱列，在保证结构稳定的同时，形成有节奏的空间层次。

The arched structure creates a covered space while allowing flexible use beneath it. As a spatial form, the arch also suggests openness and welcome.

In timber construction, a single arch can extend into a sequence of arches, providing structural stability while creating a clear spatial rhythm.
