摘　　要：首次报道了应用电阻应变片测试冻土应变,并据以确定冻土弹性常数—弹性模量E、泊松比μ的一些初步进展。所述的贴片工艺方法简便、可靠易行,其测试结果与文献报道相近。This paper reported the primary results of making use of strain gauge in measuring the strain of frozen soil successfully. By means of this method, the elastic coefficients of frozen soil such as E & μ can be measured. The tests show that a correct technique to stick strain gauge is the key whether it can be used in the measurement of mechanics of frozen soil excellently. The technique presented in this paper is convenient, reliable and easy to practise. According to the results obtained by tests, the elastic coefficients E & μ. agree with the data conducted by others.
