With the shallow geothermal energy widely using in industry and residents? livelihood,the test technology of rock and soil thermal physical index develops quickly. Meanwhile the method of testing is updating continuously. The steady plate heat flux gage method which is used in testing conductivity are adopted by most laboratories because of its accuracy,simply operation and low cost. But for the lack of interrelated rule,the deviation of result in the course of testing is inevitable. Take DRPL-Ⅱfor instance to discuss this method?s operation points,attention and result analysis. According to the sample date,the method can meet the requirements of testing technology of this iudustry,and provide reliable meth-od for obtaining numerical heat trausfer coefficient of indoor geotechnical sample.
