摘要
介绍了临长高速公路路堑开挖中通过采用宽孔距爆破、光面爆破、孔间微差与孔内分层微差爆破等控制爆破技术 ,使边坡平整稳定 ,块度均匀 ,改善了爆破质量 。
In this paper, controlled blasting techniques in LinXiang-Changshang expressway's cutting excavation, including wide-space blasting, smooth blasting, millisecond blasting between holes and layered millisecond blasting in holes are introduced. By using these techniques, the side-slope is more even, block is well-proportioned, blasting quality is improved, and construction tare of progress and ambience safety can be ensured.
