The particle analysis test is one of the conventional tests of the soil, and the particle analysis test is carried out on the soil sample, so that the content of each particle group in the soil particles can be quantitatively described, and a basis is provided for engineering classification of the soil and understanding of engineering properties of the soil. In the liquefaction discrimination of foundation soil, the clay content of the soil is required, which requires quantitative analysis of the clay content by a particle analysis test. Therefore, the particle analysis test is one of the most important test items in the geotechnical test. The particle analysis test method mainly comprises a screening method, a densitometer method and a pipette method, wherein the particle size range of the soil suitable for the screening method is 0.075-60mm, and the particle size range suitable for the densitometer method and the pipette method is less than 0.075 mm. When the powdery clay is used as an analysis sample, since the gravel is too much, if only 30g of the sample is taken, the last reading is not representative, so in the actual test, some dried soil samples are weighed as appropriate, but the greater the mass of the sample is, the greater the difficulty of controlling the washing liquid to 1000ml is, if the washing liquid is excessively large, the sample is required to be taken again, and the test steps of the GB/T50123-2019 geotechnical test method standard are repeated.
