基于正装迭代法的斜拉桥初始张拉索力计算

以某双塔双索面预应力砼斜拉桥为背景,在既定施工工序下为了使成桥后结构内力和线形达到预定合理成桥状态,利用正装迭代法基本理论,以合理成桥状态下关键参数作为目标函数、索力作为施调向量,求解斜拉索的初始张拉力。结果表明,基于正装迭代法计算的斜拉桥施工状态下初始张拉索力较精确,可达到合理成桥状态,且计算简洁、快速。     

A Subsection Shared Restoration Method for Long-Haul WDM Networks

A novel restoration scheme, Parted Path Shared Restoration (PPSR), was proposed. The major idea of PPSR is the strategy of ‘parted disposal‘. PPSR keeps the advantage of Path Based Shared Restoration (PBSR) in utilization of capacity. In addition, the restoration time of PPSR is much less than that of PBSR. Furthermore, a satisfaction function was proposed to estimate the performance of PPSR. This function takes the utilization of capacity and restoration time, into a harmonious and uniform frame. Through theoretical analysis and computer simulation, the performance of PPSR was demonstrated.
