摘要
随着高层建筑物的增多，钻孔灌注桩作为建筑物的基础被广泛应用于各种工程中。但是由于地下岩土环境的复杂性及桩基施工时人为因素的影响，往往会发生断桩事故。本文结合注浆法处理钻孔灌注桩断桩的实际工程，归纳总结了注浆法处理断桩的施工工艺及其作用机理，并提出一些建议，希望能够为类似的工程提供一些参考。
Along with the increase of high-rise buildings, bored piles are widely applied in all kinds of projects. However, due to the complexity of the underground geotechnical environment and artificial factors influence when pile foundation construction, happening cracked cast-in-situ bored pile accidents frequently. Combining with grouting method of handling cracked cast-in-situ bored pile accidents in actual engineering, summarizes the construction technology of processing cracked pile with the grouting method and its mechanism, and puts some suggestions for similar project hoping to provide some references.
