摘要
根据空腹式双曲拱渡槽的特点 ,进行结构力学分析 ,对拱式渡槽的关键部位即拱脚与槽台的结点约束力进行解除。采用双侧失稳爆破方案 ,使槽身及支撑结构一次性坍塌 ,然后对槽台进行钻孔爆破拆除 。
According to characteristics of empty-stomach double-arch groove, the structural mechanics is analyzed to remove the hold knot between arched foot and stage. The measures of busied unsteady explosion and are taken once-through collapse can be done. The trough hold was done by drilled explosion. Therefore, economical and security efficiency can be got.
