水泥改性土生产工艺有土料翻晒、碎土、改性土拌制、运输、碾压、削坡等工序，其中碎土工艺是针对膨胀土处理施工增加的特殊工艺，在国家颁布的水利工程定额中无此子目。通过对碎土工序人工、材料、机械的消耗量进行分析研究，确定碎土工序预算定额。根据定额成果，测算每方碎土单价在4～5元左右。本预算定额已经由南水北调中线干线工程建设管理局颁布实施。

The production process of cement-modified soil includes as sun baking, breaking, mixing, transporting, crushing, and cutting slopes, and soil breaking is a special process added into the construction of expansive soil, which is not included in the national irrigation quota. Based on the research of the consumption of labor, materials, and machines in the breaking process, the budget quota of breaking process was determined. The budget quota showed that the price of the broken soil is about 4~5 yuan/m3. This budget quota was enacted by the Middle Route of South-to-North Water Diversion Project Construction Authority.
