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。

Abstract:
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.
Key words:  coefficient of consolidation, piezocone penetration test, pore pressure dissipation test, in-situ consolidation coefficient
