Common standards and codes related to geotechnical tests are as follows: (1) the railway engineering geotechnical test method "(TBJ102-96) (2) the geotechnical test method standard" (\ t50123-1999) (3) "road geotechnique test procedures" (JTJ051-93) (4) the water?conservancy geotechnique test procedures in the "(SL237-1999) (5) the railway subgrade construction specifications, TB10202-2002 (6) the highway roadbed construction technology standard" JTJ033-950 geotechnical test in the regular program. (1) water content, density, proportion; (2) analysis of the particle size , liquid limit, plastic limit; (3) maximum density and minimum density of sand; (4) compaction?test, bearing ratio test.
Now the national standard is "GB\T50123-1999 geotechnical test method standards", the Ministry of transport is "E40-2007 JTG highway geotechnical test procedures", "E51-2009 JTG highway engineering inorganic binding material stability test procedures".
1, drying method: Measuring the water content. 2, cutting-ring method, sand cone method: Measuring its density. 3, Pycnometer method: Measuring specific gravity of soil particle 4, statocone tyoe liquid limit device method, method of liquid-plasitc combined tester: Test of marginal moisture content 5, compaction test: Measuring the optimum water content 6, infiltration test: Test of permeability coefficient 7, direct shear test: Test of shear strength 8, triaxial?test, unconfined compression strength test: Measuring mechanical strength of the soil sample 9, consolidation test: Test of properties of soil consolidation
