, 2019 为了快速评估既有桥梁的安全性,研究了基于多源实测信息快速准确识别桥梁影响线的方法。首先利用桥梁动力响应及车辆移动的实测信息,建立影响线识别的数学模型。在模型中引入Tikhonov正则化方法以解决病态矩阵求解问题,通过设置罚函数项以取得较光滑并贴近真实的影响线。然后通过基函数扩展法重构影响线,将其表示为一系列三次B样条基函数的线性组合,从而将问题从识别众多影响线因子简化为识别少量基函数权重系数。为了验证上述方法的可行性,先在实验室模拟钢制试验小车在钢筋混凝土三跨连续梁模型上移动的过程 ...

A link between increased temperature and avian body condition in a logged tropical forest
Conservation Biology, EarlyView.Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.

Impact Resistance Evaluation of Pier Structures Subject to Corrosion in Marine Environments [PDF]
, 2016 考虑大量桥梁未设置安全岛或其它类型的防撞设施，桥墩客观存在着船撞的风险，并可能因为船撞产生局部破坏甚至整体倒塌。与此同时，桥梁还不可避免地受到腐蚀引起的性能退化，特别是海洋环境下钢筋混凝土桥梁出现的腐蚀劣化问题尤为突出。目前对于旧桥的抗冲击性能评估，鲜有学者考虑结构腐蚀劣化带来的影响，这可能造成评价结果偏于不安全。因此，有必要细致考虑腐蚀因素对桥墩柱性能的影响，在此基础上，进一步分析墩柱腐蚀对其抗冲击性能的影响。 本文首先根据结构腐蚀劣化的机理及其对桥墩柱结构的危害，确定结构腐蚀退化因素 ...
