中文摘要：
进行一座主跨1400m的部分地锚式斜拉桥的方案试设计，通过成桥状态结构受力分析探讨该桥型的静力性能，同时证明该方案是成立的。相对于全自锚式斜拉桥，该桥型具有材料用量节省、极限静风工况结构响应改善、静力稳定性和施工状态颤振临界风速提高等诸多优点。
英文摘要：
The trial design of a proposed partially ground-anchored cable-stayed bridge with a main span 1 400 m is made. The static performance of the bridge is studied through the mechani- cal analysis of the bridge in completion state and the bridge is proved to feasible. In comparison to the fully self-anchored cable-stayed bridge, the proposed bridge has lost of advantages like the material saving, improvement of the structural response under ultimate static wind load and enhancement of the static stability and fluttering critical wind speed in construction state.
