［摘要］为准确模拟塔架与拉线组合结构的空间受力特性，采用ANSYS软件，建立三维空间精细化有限元模型，分析该结构的强度与稳定性，对比该塔架有无拉线这2种情况下结构的静力性能和自振特性。研究结果表明：塔架-拉线组合结构整体表现出侧向有弹簧支座的连续梁的受力特性；拉线使结构的受力分布合理化，提高了结构的承载力和刚度。

Abstract: In order to accurately simulate the space mechanical characteristics of the composite structure of the tower with stay wires, a precise three dimensional space finite element model was established by ANSYS, and the structural strength and stability were analyzed-Meanwhile, the static performance and vibration characteristics of towers with stay wires were compared with towers with none wires-The results show that the mechanical characteristics of the composite structure are similar to continuous beams with lateral bearing spring-The stay wires rationalize the force distribution on structures, and enhance the structural bearing capacity and the structural stiffness.

Keywords: hydrological tower; finite element; strength; stability; dynamic property
