摘要
不同直径的取土器对土样扰动的影响程度不同 ,恰当选择取土器的直径 ,对取土质量是非常重要的。直径过小 ,不能保证取土质量 ;直径过大 ,增加钻探费用。本文强调有条件和经济允许的话 ,应该优先考虑大直径的取土器。
The disturbance of soil sample varies with the diameter of sampler. It is very important to choose the diameter of sampler properly because smaller diameter sampler can't guarantee sample quality and bigger one will increase boring cost. The author suggests using bigger diameter sampler under favorable conditions.
