摘　　要：依托南京轨道交通九号线初勘工程,探讨了固结试验测定基床系数的方法,并与扁铲试验数据和地区经验数据对比,提出了基床系数修正建议,提高了试验成果的可靠性。Based on the preliminary geotechnical investigation project for line 9 of Nanjing subway, the coefficient determination method of subgrade reaction is discussed using consolidation test. As the test results are contrasted with flat dilatometer test results and regional experience data, the modification suggestion for coefficient of subgrade reaction is proposed to improve the result’s reliability.
