摘　　要：大型弧形闸门斜支臂空间角度易出现混淆和错误,且其微小的误差会造成结构上的很大误差,影响弧门的制造、安装及运营安全。因此,对弧门斜支臂的几个关键空间角度进行定义区分和计算,并以实际工程弧形闸门为例,分析斜支臂各关键角度对闸门制造和安装精度的影响程度,进而提出可提高制造和安装精度的措施,以供后续斜支臂弧形闸门设计、制造和安装参考。The space angles of inclined supporting arm of large radial gate are easily confused and mistaken, and its small errors may cause large structural errors, which will affect the manufacturing, installation and safe operation of the radial gate. Therefore, this paper defined, distinguished and calculated several key space angles of the radial gate inclined supporting arm. Taking an actual project radial gate as an example, the influence extent of each key angle of the inclined supporting arm on the manufacturing and installation accuracy of the gate was analyzed. Furthermore, this paper put forward several measures to improve the manufacturing and installation accuracy, which can be used as a reference for the subsequent design, manufacturing and installation of radial gate with inclined supporting arm.
