摘　　要：本文以高港枢纽二线船闸为例,通过对比空心钢管、型钢两种不同空间桁架结构型式的闸门,采用实腹式轴心受压构件的稳定性计算方法,分析比较两种结构杆件稳定性的大小。从杆件受压失稳的角度分析得出,三角闸门设计使用空心钢管截面的空间桁架杆结构比型钢截面的空间桁架结构更合理,为三角闸门空间桁架杆件选择提供一定参考依据。In the paper,Gaogang Hub Second-line Shiplock is adopted as an example,the stability calculation method of solid-web axial compression members is adopted by comparing two gates with different space truss structure modes made of hollow steel tube and section steel. The stability of two structural members is analyzed and compared. It is concluded through analysis from the perspective of member compressive instability that application of space truss member structure of hollow steel tube cross section in triangle valve design is more rational than the space truss structure of section steel cross section,thereby providing certain reference basis for selecting triangle gate space truss members.
