| 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。

| Abstract: | The quality o f cement2modified soil filling constructio n is an im po rtant facto r affecting the stability o f channel slope in
the ex pansiv e rock( so il) reg ions. Accor ding to the replacement situation of cement2modified so il in t he South2t o2Nor th Wat er Di2
v ersion Project, a new cement2modified so il filling co nstr uction metho d, concentr atio n f ield mix ing metho d, w as pr oposed based
on the analysis o f the field roller com pactio n experiment results of road m ix ing metho d and plant mix ing method. The new meth2
o d can ov ercome the disadvantages of road mix ing metho d and plant mixing metho d, and has been successfully applied to the ce2
ment2modified soil filling co nstr uct ion in t he Middle Route of South2to2Nor th Water Diversion Pro ject, w hich can pr ov ide r efer2
