摘　　要：水泥改性土填筑施工质量是影响膨胀岩(土)地区渠道边坡稳定性的重要因素。针对南水北调工程水泥改性土换填的实际情况,通过对传统路拌法、拌合站厂拌法施工工艺现场碾压试验结果的分析研究,提出了一种新的水泥改性土换填施工方法——集中场拌法。该方法克服了路拌法和拌合站厂拌法的缺点,已成功运用于南水北调中线工程水泥改性土换填施工中,为类似工程的施工提供了参考。The quality of cement-modified soil filling construction is an important factor affecting the stability of channel slope in the expansive rock（soil） regions. According to the replacement situation of cement-modified soil in the South-to-North Water Diversion Project, a new cement-modified soil filling construction method, concentration field mixing method, was proposed based on the analysis of the field roller compaction experiment results of road mixing method and plant mixing method. The new method can overcome the disadvantages of road mixing method and plant mixing method,and has been successfully applied to the cement-modified soil filling construction in the Middle Route of South-to-North Water Diversion Project, which can provide reference for the similar engineering projects.
