| 摘 要： | 选取南水北调中线工程平顶山段中膨胀土作为试验标本，通过室内和室外的碾压试验、滴定试验以及膨胀率试验研究了水泥改性土的某些性质，为水泥改性土的设计施工提供参考。水泥改性土有效降低了膨胀土的膨胀率，增加了土体的稳定性，保证了南水北调工程平顶山试验渠段改性土换填施工质量。

| Abstract: | Selecting the swelling soil from the Pingdingshan section of the Middle Route Project of South -to-North Water Diversion as the test sample ,certain properties of the cement modified soil were studied through the indoor and outdoor compaction test ,the titration test and the expansion rate test ,w hich gives a reference to both design and construction of the cement modified soil .The cement modified soil effective-ly reduces the expansion rate of the swelling soil and increases the stability of the embankment ,thus ensu-ring the cement modified soil embankment construction quality of the Pingdingshan section of the south -to-north water diversion project by replacing the swelling soil . |
