These measurements are used to produce a continuous profile of normalized blow counts that are repeatable, unaffected by varying driving energy or accumulated shaft resistance, and can be used to directly estimate equivalent SPT N60 blow count values as per DeJong et al. and Ghafghazi et al. ...
Use of CPTu to estimate equivalent SPT N60 Although the CPTu offers many advantages over the SPT, it may be desirable in some instances to use SPT-based experience of soil behavior. An algorithm is ... HJ Pincus,MG Jefferies,MP Davies - 《Geotechnical Testing Journal》 被引量: 172发表: ...
程序自动对SPT现场数据(N)应用以下校正,以获得N60和N1(60): 钻孔尺寸 取样方法 杆长度 能量水平 覆盖层应力矫正(涵盖9种方法) 水位校正(可选–用于N60≥15时的承载力分析) 2、使用正确的相关性! 每种相关性都是针对某些土壤类型开发的。NovoSPT知道这一点。在特定深度,基于场地地层,NovoSPT仅使用为该类型土...
Therefore, SPT hammer efficiency shall be measured and used to correct the SPT N value. The resulting number is known as N60. The corresponding N60 value is then used to obtain soil properties such as friction angle, which in turn is used for the evaluation of allowable bearing capacity ...
SPT CAL Since 2010 we have performedSPT Hammer Energy Measurementsfor standard penetration test hammers to get efficiency ratings which can then be used to adjust blow count N values to a normalized N60 value. This is sometimes called aHammer Calibration,Hammer Energy Calibration, Hammer Energy Tes...
