The significance of piezocone penetration test

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.
