摘要
简要分析了我国CPT技术与国际CPT技术的差距,介绍了现代多功能CPTU测试系统、应用于CPT的传感器技术的发展、现代多功能CPTU技术的优势及SCPTU、RCPTU、VisCPT技术的新应用。同时,分析了软土地区多功能CPTU测试技术要点,包括测试计划的制定、孔压系统的饱和与标定、测试精度的保证、负值的分析及探头的保养等问题。
The differences between domestic cone penetration technology（CPT） and international cone penetration technology were analyzed in the text.The authors introduced the modern multifunctional CPTUtesting system,the development of sensor technology applied in CPT,the advantages of modern multifunctional CPTUtechnology and the newapplications of seismic piezocone penetration test（SCPTU）,resistivity piezocone penetration test（RCPTU） and VisCPTtechnology.Meanwhile,the authors analyzed the testing points by multifunctional CPTUin soft soil area,these testing points were consisted of testing plan constitution,the saturation and demarcation of cone pressure system,the guarantee of testing precision,the analysis of the negative and maintaining of the probe.
