| 摘 要： | 简单介绍先进的无绳孔压静力触探技术,并分别探讨由孔压静力触探试验估算软土层固结系数、不排水抗剪强度和侧向渗透系数的原理以及估算方法,并结合江苏淮盐高速公路试验段对地基土的土性参数进行估算。通过与其它常规原位测试试验结果的分析对比,发现由孔压静探资料对土层的以上参数进行估算是可行的,值得在公路建设的勘察及设计中推广应用。

| Abstract: | This paper simply introduced the technology of advanced non-cable piezocone,and discussed the theories and methods to determine the coefficient of consolidation,undrained shear strength,lateral coefficient of permeability of soft soils by piezocone test (CPTU).Combined with the investigation carried out in the experimental section of Yan-Huai Expressway,the parameters of soil properties were estimated.Comparison with the test results of the laboratory tests and other in-situ test,like vane shear test indicated that the results from CPTU are credible,and it would be worth applying the CPTU technology in the investigation and design of highway. |
