摘　　要：在总结当前水泥土搅拌桩质量检测的要点和检测方法的优缺点基础上,通过在珠江三角洲地区的多项公路工程水泥土检测试验,提出了短期和长期相结合、多项检测方法相结合的水泥土搅拌桩检测体系,对搅拌桩质量检测的频率、方法、指标、评定标准进行了详细的阐述。工程实践证明,采用这种系统的检测方法,可以满足水泥土搅拌桩的检测要求。Through summarizing the key points of the quality tests of mixing column with cementtreated soil and the advantages and disadvantages of test methods and some field experiments in multiple expressway projects in the Pearl River Delta area, a testing system for mixing column with cement-treated soil of a combination of short-time tests and long-time tests and several test methods is put forward. Frequency, method, parameters, evaluation criteria of quality testing are also explicated in this paper. The engineering practices show that the application of such systematic testing method can meet the requirements of testing cement mixing column.
