摘要
本文简单介绍了多功能孔压静力触探仪器设备及测试技术,分别探讨由孔压静力触探试验确定软黏土层固结系数及不排水抗剪强度、渗透系数的原理及方法,并结合江苏华电句容发电厂工程对软黏土的土性参数进行分析。通过与其它常规室内固结试验及原位测试试验结果的分析对比,得出由孔压静力触探探试验确定软黏土的以上参数的规律性和差异性。
In this paper,the equipments and technology of cone penetration test with pore pressure measurement(CPTU) are briefly introduced,and the principles and methods based on CPTU to determine consolidation coefficient and undrained shear strength and permeability coefficient are discussed.According to the investigation data of Huadian Jiangsu Jurong Power plant,parameters of soft clay soil properties based on CPTU are analyzed.By comparison with the results from laboratory tests and in-situ tests,the regularity and difference of parameters of soft clay soil properties are analyzed.
