Jianzhu Gangjiegou Jinzhan, 2005 深圳会议展览中心钢结构工程采用高强度、大直径预应力锚栓,用以锚固铰支座和拉接端头梁,由于设计要求先张拉后灌浆,所以预埋材料涉及了锚栓、锚板、波纹管、注浆管等。每一材料的质量和施工过程都必须严格控制,否则,将给张拉和灌浆工序带来很大困难,加上28.9m、45.0m处为高空作业,又加大了预埋、张拉的难度,使用合理的预埋方法和张拉工装是解决该工序的重要手段。本文主要介绍了该工程高强预应力锚栓预埋、张拉及灌浆的技术。

Integrative Conservation, Volume 3, Issue 4, Page 426-437, December 2024.Globally, human‐use landscapes are being reported to be large carnivore habitats. The study examines the spatial variation of leopard density in the forest‐human use landscape mosaic of the Duars region of West Bengal. Tea estates overshadow forested areas in terms of the absolute density of leopards, reiterating the potential of human‐use areas to be ...

Integrative Conservation, Volume 3, Issue 2, Page 134-141, June 2024.Potential distribution scenarios of Ophiophagus hannah in current and future climate change scenarios indicate highly suitable areas for this reptile will increase over the period and will shift towards the north of Asia. This may have a prospective alteration in human‐snake encounters in these areas of Asia accordingly.
