| 摘 要： | 不同直径的取土器对取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，会增加钻探费用。在润扬大桥北锚碇科研项目中，对取土质量进行了试验研究，试验结果表明，在经济条件许可的情况下，应该优先考虑大直径的取土器。

| Abstract: | The disturbance of soil sample varies according to diameter of sampler. It is very important to choose diameter of sampler properly because the too small diameter sampler can't guarantee quality of soil sample and the too big one increases bore costs. Experimental investigation was proceeded for sampling quality in scientific research item of the north concrete anchor of Ruyang bridge. The test result shows the large diameter sampler should be chosen if economic condition is available. |
