钢拱架轴力主要为压力,仅在拱顶和拱脚等较少部位出现拉力。下台阶边墙开挖之前,钢拱架各部位轴力为负值,均处于偏心受压状态;下边墙开挖后,拱顶轴力变为拉力,分析认为下台阶边墙的开挖,造成钢拱架底部悬空,使钢架在上部围岩压力和侧压力的合力作用下,发生下沉和向临空面收敛变形两种运动趋势,致使拱顶钢架出现受拉的情况。</span>

资料统计,工程渗水70%是因施工缝处理不当造成的,工程渗水造成施工作业差,无形中了施工难度,严重影响施工进度。渗水会对围岩进行侵蚀,使围岩性,冲掏衬砌背后围岩形成空洞,威胁衬砌。在阶段,渗水会加快内部结构的锈蚀,影响结构的受力,长期渗水容易使衬砌剥落、风化,的使用可靠性;若含有侵蚀介质,将造成衬砌劣化,衬砌的承载能力。</span>

格栅钢架各组成部件焊接完成后,进行试拼装,以检验格栅钢架的几何尺寸,各部件的螺栓节点以及焊接等。首榀试拼合格后,进行验收,而后进行批量生产,并按规定抽样进行批量验收。</span>
