冲孔灌注桩是在复杂地质条件下，地基基础工程中较为常见的成桩形式。本文重点介绍了灌注桩内多层岩石区域内的一种原位超前爆破成孔工艺。破碎地下孤石，达到加快后期冲孔进尺与成桩进度，提高了工效与保证质量效果。
遲孔灌註樁是在複雜地質條件下，地基基礎工程中較為常見的成樁形式。本文重點介紹瞭灌註樁內多層巖石區域內的一種原位超前爆破成孔工藝。破碎地下孤石，達到加快後期遲孔進呎與成樁進度，提高瞭工效與保證質量效果。

The punching bored pile is the common form of pile foundation engineering under complex geological condit-ions. This article mainly introduces a pore forming process of situ advance in the area of multi-layered rock of cast-in-place pile, breaks the underground stones to speed up the late punc-hing footage and the progress of pile, and improve the working efficiency as wel as guarantee the quality effect.
