大跨度半漂浮体系斜拉桥索力优化研究

摘要

Taking a large span semi-floating system cable stayed bridge for example, this paper established the cable force optimization model, using the bending energy minimization optimization method, taking the structure bending strain capacity for objective function to make cable force optimization, gained a better finished dead state.%以某大跨度半漂浮体系斜拉桥为例，建立索力优化模型，采用弯曲能量最小的优化方法，以结构的弯曲应变能为目标函数来进行索力的优化，得到了较优的成桥状态。
