摘　　要：微型钢管桩试验及地基加固施工结果表明微型钢管桩施工中控制水泥及石子的用量,采用二次注浆是保证加固效果的关键;在有碎石填土的地区,微型钢管桩头部形成貌似图钉状的扩大头,能明显提高桩及地基承载力,减小沉降。Based on the result of the micro steel tube pile test, it shows that the dosage of the cement and gravel in micro steel pipe piles during foundation reinforcement construction, and the key to guarantee the reinforcement effect by the secondary grouting. The micro steel tube pile head seems like a expanded pin in rubble filled region, which can obviously increase the pile and the bearing capacity of foundation, and reduce subsidence as well.
