摘　　要：结合“同三”国道高速公路宁波市境内试验段的软基加固试验工作，通过大量的现场孔压静力触探试验（CPTU）来探讨利用孔压静力触探测定软粘土的原位固结系数。文中介绍了仪器设备、（CPTU）的试验方法、资料的整理以及试验结果与室内试验测定的固结系数的对比，讨论了Ch、Cv指标之间的差异性和规律性。The CPTU test results of strengthening soft foundation of Tongsan highway in Ningbo city are presented in this paper. It is discussed to determine the coefficient of con-solidation of soft clay from pore pressure measured by CPTU tests. The equipement, op- eration and calculation were intrnduced, and the results were compared with the test data measured by laboratory. At last the difference of Ch and Cv was discussed.
