摘要
本文综述了目前使用的常规取样技术取样质量评价的研究成果,介绍了现场控制冻结取样的原理和实施方法。以试验成果为依据,划定了冻结法的适用范围,提出了控制土样扰动的指标。文章认为,在控制条件下,现场冻结法能取得高质量的原状砂。
The research results of evaluation of sampling quality by current conventional sampling technique are summarized in this paper. The principle of in-situ control freezing sampling and its implementation are introduced. Based on the test results the range of application of the freezing process is defined and index to control the disturbance of sample is proposed. The author believes that undisturbed sand of high quality can be sampled by in-situ freezing process under controlled condition.
