摘　　要：为改善传统灌注桩施工质量较低的问题,本文开展了对泥浆护壁钻孔灌注桩施工质量控制方法的全面研究。通过优化浆液配合比、设计灌注桩垂直度与深度、控制泥浆护壁钻孔作业质量、灌注桩成桩保护,提出了一种全新的灌注桩施工质量控制方法,并制定了质量通病防治措施。实例分析可知,新的控制方法能够显著提升灌注桩竖向抗压承载力。In order to improve the problem of low construction quality of traditional cast-in-place piles,this paper conducts a comprehensive study on the construction quality control methods of slurry wall protection and bored cast-in-place piles.A brand new construction quality control method for cast-in-place piles is proposed by optimizing the slurry mix ratio,designing the verticality and depth of cast-in-place piles,controlling the quality of the slurry wall protection boring operation,and protecting the cast-in-place piles formation.Measures for preventing common quality problems are formulated.Case analysis shows that the new control method can significantly improve the vertical compressive bearing capacity of cast-in-place piles.
