摘要
结合青藏铁路桥梁施工实际,对多年冻土区钻孔灌注桩干法成桩施工技术进行了研究和探讨,得出了采用旋挖钻机干法成孔施工钻进速度快的结论。
Combined with practical bridge works in Qinghai-Tibet railway the dryjet mixing construction technology of cast-in-place bored pile in permafrost region is studied and discussed. Practice shows bored pile by churning drive and dry construction speed up construction progress.
