Abstract: As the basic method to obtain rock and soil’s physical-mechanical parameters, the soil test plays an important role in engineering design, construction and quality inspection. According to the experiences of doing experimental work over the years, the author offered their thoughts on a number of related issues. ①Taking the soil sample of a power plant in Tangshan for example, the mechanical properties of a special sand with certain clay in it ,which is widely distributed in Hebei and Inner Mongolia are discussed. ②Combining with the test requirements in technical standards, some viewpoints on "the pressure of consolidation" and "continuous loading with strain control " in consolidation test, are put forward. ③For the characteristics of unsaturated soil with less water content in the northern region, the reasons why the soil shear strength test is difficult and the results are not exact, are analyzed. Finally, some advices in favor of practical applications in projects are proposed

Key words: clay content, sand, unsaturated soil, classification, consolidation test, shear strength test
