摘要
南水北调中线工程总干渠全长1432km,渠线穿越膨胀土(岩)地层累计长度约340km,其中膨胀岩渠段长169.7km,膨胀岩因其特殊的工程特性,易造成渠坡失稳,对工程的安全运行影响很大,换填水泥改性土是膨胀岩处理的方法之一。本文就南水北调中线工程总干渠宝丰郏县段第三施工标段膨胀岩换填水泥改性土施工为例,对水泥改性土填筑的控制指标、施工工艺、实验检测和质量控制等作简要总结。
The total length of 1432 km of the main canal of south-to-north water transfer project, the canal through expansive soil strata （rocks） total length of about 340 kin, the expansion of rock channel 169.7 km long, expansive rock because of its special engineering properties, easy to cause the canal slope instability a great influence on safe operation of the project, in filling modified cement soil is one of the processing method of swelling rock. In this paper, the main canal of south-to-north water transfer project in baofeng jiaxian bid section of third construction expansion rock in filling modified cement soil construction as an example, the control of the modified cement soil filling index, construction technology, test and quality control, etc. A brief summary
