| 摘 要： | 塌孔、缩径是桩基成孔施工中经常出现的问题，成孔的质量直接影响钻孔灌注桩桩体的质量。目前的成孔施工中除了下套管之外最有效的护壁方法就是采用防塌泥浆护壁。通过对各种组分泥浆试验性能参数的比较与分析，优选出防塌泥浆最佳配方，从而提高钻孔灌注桩成孔施工中孔壁的稳定性。

| Abstract: | Hole collapse and diameter shrinkage often occur in the pile foundation borehole construction, the borehole qual-ity directly affects the quality of the bored grouting pile.Except for casing in borehole construction, the most effective wall protection method is by sloughing mud.Through the comparison and analysis on various mud with ingredients, the best for-mula of collapse preventing mud is selected to improve the stability of hole wall in bored grouting pile construction. |

| Keywords: | pile foundation borehole construction anti-sloughing mud performance parameter |
