It is commonly assumed that dry and saturated sands exhibit similar cone resistance–relative density relationships. Some studies pointed out that partial saturation and calcareous sands with considerable fines content are potential factors affecting these relationships. However, there is experimental evidence in Shaqour Bull Eng Geol Environ 66:59-70, (2006) that clean uncemented quartz sand may exhibit lower cone resistance in saturated conditions. The present study aims on contributing towards better understanding the effect of water saturation on cone resistance in sand. For this purpose, Ticino sand samples were prepared dry and saturated in a calibration chamber and cone penetration tests were performed over a wide range of relative densities and at two consolidation stresses. Overall, it was observed that dry and saturated samples exhibited similar cone resistances. Only slightly higher cone resistances were observed for dry samples at the lower consolidation stress. Two anomalous samples, which were tested dry at medium relative density, were found to exhibit way higher cone resistances than expected from published cone resistance–relative density relationships. The Young's modulus was observed to be proportional to cone resistance and independent of whether a sample was tested dry or saturated, being therefore considered as more robust soil property for cone resistance relationships.

通常假定干砂和饱和砂表现出相似的锥阻力-相对密度关系。一些研究指出，部分饱和和含钙细砂含量较高的钙质砂是影响这些关系的潜在因素。但是，在Shaqour Bull Eng Geol Environ 66：59-70，（2006）中有实验证据表明，清洁的未胶结石英砂在饱和条件下可能显示出较低的耐锥性。本研究旨在帮助更好地理解水饱和度对砂土锥孔阻力的影响。为此，在校准室内将提契诺州的砂岩样品干燥并饱和，并在很宽的相对密度范围内和两个固结应力下进行锥入度试验。全面的，据观察，干燥和饱和样品表现出相似的耐锥性。对于干燥样品，在较低固结应力下仅观察到稍高的锥抗性。发现两个异常样品在中等相对密度下进行了干燥测试，发现其圆锥电阻远高于根据公布的圆锥电阻与相对密度的关系所预期的值。观察到杨氏模量与耐锥度成正比，并且与测试样品是干燥还是饱和无关，因此对于耐锥度关系而言，杨氏模量被认为是更坚固的土壤性质。被发现表现出比根据公开的锥电阻-相对密度关系预期的更高的锥电阻。观察到杨氏模量与耐锥度成正比，并且与测试样品是干燥还是饱和无关，因此对于耐锥度关系而言，杨氏模量被认为是更坚固的土壤性质。被发现表现出比根据公开的锥电阻-相对密度关系预期的更高的锥电阻。观察到杨氏模量与耐锥度成正比，并且与测试样品是干燥还是饱和无关，因此对于耐锥度关系而言，杨氏模量被认为是更坚固的土壤性质。
