摘　　要：在泥浆护壁灌注桩工程中,钻孔深度、沉渣厚度和导管浇筑混凝土三个质量指标对桩承载力、造价和工期的影响较大,但现行规范有关规定不尽完善,工程实践中问题较多。通过工程实践经验和理论分析相结合的方法,提出控制这些质量指标的建议。In slurry sediment thickness and construction cost and applicable codes and indexes are proposed breast wall filling pile engineering, three quality indexes including drilling depth, tremie concrete placing, have important influence on bearing capacity of pile, construction schedule. However, relevant there are many problems in engineering provisions for these aspects are not complete in practices. Suggestions on quality control of these through combination of practical engineering experiences and theoretical analysis.
