Based on the case of arc-drum shell structure,combined with construction experience,block adding hoisting method is adopted,including precast segmental,hoisting combination and whole hoisting with adding grid.
基于拱形筒壳结构实例,结合以往的施工经验,采用分块添加式提升法,即分段预制、吊装组合、整体提升添加网格,对结构进行施工,确保了施工的安全性。
Arched top pillars are introduced based on the results of finite elementary numerical analysis.
根据有限元数值分析结果 ,确定采用拱形顶柱 ,并对上盘层状岩体采用螺旋状长锚索加固技术 ,保证了白银深部铜矿高应力区空场开采的顺利进
