摘要
孔压静力触探(CPTU)是20世纪80年代在国际上兴起的新型原位测试技术,因其诸多优点,目前在欧美诸国已得到广泛应用。由于探头规格、技术标准和操作程序的差异,影响CPTU测试成果的因素很多,而且其影响程度也各不相同。根据前人的研究成果,对CPTU测试成果的影响因素进行了分析总结,以期在CPTU资料整理和应用中引起重视。最后,简要论述了考虑诸多影响因素的原始数据修正方法。
As an in -situ test technique originated in 1980s, the piezocone penetration test （CPTU） has been attracting wide attention and widely used in the western country because of its advantages. Due to the differences in equipment design, technique code and operation method, there are lots of general factors affecting interpretation for the CPTU data. On the basis of the past investigation, the general factors affecting interpretation for the CPTU data are analyzed and summarized for the sake of attracting attention in use of the CPTU data. The corrections on various factors that influence primary measured data are described in brief.
