摘要
本文探讨了根据孔压静探试验在高速公路地基勘察中应用的相关理论和方法。并以淮盐高速公路试验段为例 ,对土层进行划分 ,并对地基土的不排水抗剪强度、固结系数等参数进行了估算。通过与其他试验结果的对比分析 ,可以得出结论 :孔压静探试验适合于估算地基土的土性参数。
The theories and methods related to the application of piezocone test(CPTU) in the investigation of expressway subgrade.Based on the t est results of piezocone tests in the investigation of the experimental section of Huai-Yan Expressway,the soil stratification is made,and the coefficient of c onsolidation and the undrained shear strength of soft clay are estimated.Compari ng with the boring records and the testing data from laboratory tests and vane s hear tests,it can conclude that CPTU is suitable to estimate the parameters of s oils.
