Jianzhu Gangjiegou Jinzhan, 2022 张弦结构由上弦刚体、下弦柔性拉杆及其之间的刚性撑杆构成。异形张弦梁钢拉杆非张拉建立预应力施工技术，即在张弦梁安装阶段对上弦刚体进行预变形处理，并调节钢拉杆的长度，再通过卸载临时支撑，上弦刚体回弹，在撑杆的作用下钢拉杆被动受拉，从而为张弦梁建立预应力，临时支撑的卸载过程即为张弦梁的加载过程。实施该方法之前先进行全过程施工模拟计算，施工过程中进行应力-应变监测，施工完成后对钢拉杆进行内力检测。结果表明，该施工技术的力学原理成立，操作简便，内力转换高效，精度满足要求，对类似工程具有参考意义。

Weaving knowledges to support wildlife health surveillance in Kenya's pastoral rangelands
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract In wildlife–livestock–human interfaces, pathogens capable of spreading between wild and domestic animals and humans have important implications for conservation outcomes, economics, and public health. Robust wildlife health surveillance can help address these risks.

International Journal of Urban and Regional Research, Volume 50, Issue 1, Page 191-220, January 2026.Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...
