摘　　要：旋挖钻机成孔施工具有低噪音、低振动、挤土不明显、对周边影响较小,成孔较快、精度较高、适应范围较广等优点,但是,塌孔是旋挖钻孔灌注桩施工过程中最常见的质量和安全事故。通过对塌孔原因进行分析,结合具体工程实例,对塌孔的处理措施进行探究及运用,为以后的施工积累经验。Rotary drilling rig drilling has the advantages of low noise,low vibration,less obvious soil squeezing,less impact on the surrounding area,faster drilling,higher accuracy,and wider adaptability.However,hole collapse is the most common quality and safety accident in the construction process of rotary drilling and grouting piles.By analyzing the causes of borehole collapse and combining with specific engineering examples,this study explores and applies measures to deal with borehole collapse,accumulating experience for future construction.
