结合具体实例，针对变径水泥土搅拌桩加固软基进行了造价分析，分析结果表明：变径水泥土搅拌桩与等径水泥土搅拌桩相比同体积工料机消耗量有所减少，相同水泥掺入比和面积置换率前提下，使用变径水泥土搅拌桩处理软基具有较好的经济效益。%Combining with specific examples, this paper made cost analysis on strengthening soft foundation of reducing cement soil mixing pile,the analysis results indicated： compared the reducing cement soil mixing piles with equal-diameter cement soil mixing pile, the same volume material machine consumption had decreased, in the premise of same cement mixing ratio and area replacement rate, using reducing cement soil mixing pile to deal with soft foundation had better economic benefit.
