Soil mechanics is a test of strong discipline, left the test and the test will not be able to develop, development of soil mechanics theory and experiment must be closely combined. Briefly summarizes the basic physical and mechanical indexes of soil test, direct shear test, three axial compression test, unconfined compressive strength test laboratory test and static load test, standard penetration test, cone penetration test, pressuremeter test method test and vane shear test field test, points out the important significance of soil test.
