斜拉桥索塔的拉索锚固区是斜拉桥的关键部位 ,受力复杂 ,一般的平面分析很难反映其实际的应力分布 ,根据艮山门斜拉桥索塔构造及预应力束布置的特点 ,设计了索塔节段足尺分析模型 ,给出了空间分析的一些主要成果及与试验实测值的比较 ,得到了许多重要结论。对指导该大桥的建设具有重要作用 The cable anchorage zone of the cable-stayed bridge pylon is a key part of the cable-stayed bridge. Due to the complicated forces, the general plane analysis is difficult to reflect the actual stress distribution. According to the structure and prestressing beam arrangement of the cable-stayed bridge Characteristics, designed a full analysis model of pylon segment, gives some main results of spatial analysis and compared with the experimental values, and got many important conclusions. To guide the construction of the bridge has an important role
