| 摘 要： | 钻孔灌注桩在基础工程中的使用在我国已相当普及，但因其属隐蔽工程，在施工过程中控制比较困难。成孔和成桩是钻孔灌注桩的二个关键部位，如质量控制得不好，则可能会发生塌孔、缩径、断桩、桩孔偏斜及桩端达不到设计持力层要求等。本文针对泥浆护壁钻孔灌注桩的施工特点，论述了在施工过程中钻孔灌注桩成孔和成桩的质量控制方法。

| Abstract: | Drilled perfusion stake has been widely applied in the foundation engineering in our country. But it＇ s very difficult to control in the construction process because it belongs to the hidden engineering. If the quality is not controlled well, it may lead to collapse of the hole, the shrinkage of the diameter, the break of the stake, the deflection of the stake hole and the stake end can not meet the requirement of designed support force layer. In light of the construction characteristics of slurry-supported drilled perfusion stake, this article discusses how to deal with the quality control of the holing and staking of drilled perfusion stake in the process of construction. |
