摘要
金塘大桥斜拉索塔端锚固采用新型的钢牛腿和钢锚梁组合结构,为世界首创。通过混凝土索塔节段足尺模型试验和空间有限元仿真计算分析,验证了其受力机理和结构可靠性。文中给出试验的主要成果,得出一些重要结论,对于该新型锚固构造的结构设计和推广具有重要的意义。
A new-type composite structure of steel corbel and steel anchor beam is firstly applied at anchorage zone on pylon of Jintang Bridge in the world.According to the full-scale segmental model test of concrete tower and analysis with spatial finite element method,its bearing mechanism and structure reliability can be well verified.The main results and conclusions obtained in this research are of great significance for the structure design and popularization of the new-type anchorage constitution.
