水泥改性土,是指将一定比例的水泥掺入膨胀土土料之中以改善膨胀土的性质或结构,使膨胀土丧失膨胀潜能,并在一定程度上提高土体强度或承载力,在膨胀土地区可以充分利用开挖料,实现土料的就地取材。南水北调中线一期工程总干渠膨胀土试验段工程(南阳段)针对膨胀土渠段采用水泥改性土换填,通过不同的拌和方法对比,分析总结其有效的施工技术工艺。
Cement modified soil refers to a certain proportion of cement incorporated into the expansive soil material to improve the nature or structure of expansive soils expansive soil loss of expansion potential and to some extent to enhance soil strength or bearing capacity in Expansive soil area can make full use of excavated material, to achieve the local materials of soil. The expansive soil test section (Nanyang section) of the main canal of the mid-south section of the South-to-North Water Diversion Project adopts cement-modified soil exchange for expansive soil channels. Through comparison of different mixing methods, the effective construction technology and process are analyzed and summarized.
