摘　　要：针对基坑硬质岩体开挖提出一种新型综合施工技术。利用绳锯将待破除岩体切割分离,在绳锯切割缝放置气袋,气袋充气膨胀后岩石沿裂隙发生破碎,有效降低下一步岩石破除难度,提高施工效率。绳锯切割及气袋顶推几乎不产生扬尘、噪声污染且对周边零扰动,在提高效率的同时实现绿色环保施工。This paper introduces a new technology to crush and remove hard rock in foundation excavation. Wire-saw is used to separate rocks and airbags are put in the wire-saw incising aperture.Then the air bags are blew up to break rocks along the crevice. This technology effectively reduces the difficulty of removing rocks in the next step while improves the construction efficiency. What＇s more,wire-saw cutting and airbag pushing hardly generates dust,noise and disturbance,which greatly improves environmental benefits.
