中文摘要：
环刀在外业工程土壤取样中有着重要的应用,传统的普通环刀在土壤取样方面有很多不足之处,为了解决环刀在土壤取样中剪切阻力大,土壤扰动大,环刀容易变形,取样慢,取样效率低等一系列问题,研制了实用新型组合环刀取样器,克服了以上缺点,并与传统的环刀法进行了对比测试与数据分析,得出了理想、显著的试验效果。从而在很大程度提升了取样速率,并保证了所取土壤的质量,保障了工程数据的准确性与可靠性。
英文摘要：
The ring knife has important application in field engineering soil sampling. Traditional ordinary ring knife has many deficiencies in soil sampling,In order to solve the problems such as cutting ring shear resist-ance in the soil sample, soil disturbance, easy to be deformed, sampling slowly and its low sampling efficien-cy, new model combination ring sampler is developed, which avoid the deficiency compared with traditional ring knife. The sampling rate is greatly enhanced thus ensuring the quality of the soil, which ensure the accu-racy and reliability of the project.
