Cable-stayed bridges are modem solutions offering important advantages: the possibility to cover large spans and through this reducing the number of substructure elements,a relative small construction depth,a good esthetic.In the design stage of such type of bridge,several parameters concerning the bridge geometry are to be considered: span length,height of the pylons,the number and distribution of stays along the bridge deck.From these,the number and position of stays plays a very important role from possible further strengthening point of view.A large number of stays together with an optimized distribution can lead to major advantages,if stays damages occur or if the strengthening of bridge is necessary in order to fulfill the new traffic requirements.

卖方分析师的每股盈余预测在实证文献中被广泛使用。该指标同时依赖于分析师对目标公司未来净利润的预测和对目标公司未来股本数量的预测。因此,如果在分析师发布预测后,目标公司的股本数量发生超出分析师预期的扩张,则每股盈余预测将无法代表分析师对目标公司未来基本面的预测。本文构建了“调整后每股盈余预测”指标,该指标可剔除超预期股本扩张对每股盈余预测的影响,真实反映分析师对目标公司未来基本面的预测。本文应用该指标,在两个具体的实证研究场景中证明了,忽略超预期股本扩张的影响可能得出错误的实证结论。本文还进一步指出了三个忽
