推广孔压静力触探技术的意义

The significance of piezocone penetration test

单桥静力触探仅能测一个参数 ,分辨率低 ,只在我国应用 ,不利于国际竞争与交流 ,建议逐步加以淘汰 ,而应大力推广国际通用的孔压静力触探技术。该技术能测多个参数 ,在划分土类、求取土层固结系数等方面精度高 。

Single bridge cone penetration test should be gradually eliminated because it measures only one parameter with low accuracy, and only used in China,unsuitable for international competition and interchange;while piezocone penetration test (CPTU) can measure many useful parameters with high accuracy in determining soil types, consolidation coefficient, etc. It is also widely used in the world. So it should be energetically spreaded in China, especially in soft soil area.
