ASTM D425-17 土壤离心湿度当量试验方法

5.1 All water contained in a saturated soil cannot be removed by gravity drainage alone. The amount of water retained after gravity drainage is usually expressed as the water holding capacity or specific retention of the soil. These values may be influenced by elapsed time, the particle-size distribution and the plasticity of the soil. In most cases, as the plasticity increases so does the moisture equivalent value. 5.2 The centrifuge moisture equivalent is determined by applying a centrifugal force great enough to reduce the capillary fringe zone sufficiently so that it can be ignored without introducing error. The centrifical force is maintained sufficiently low as not to withdraw a large proportion of the water that is held securely above the capillary fringe (see Note 1). 5.3 It has been determined that for at least medium-textured soils (sandy to silty particle-size distribution) the centrifuge moisture equivalent approximates the water holding capacity and when combined with the bulk density can be used to calculate an approximate specific retention and specific yield. These properties when combined with porosity can be used to estimate aquifer storage coefficient. Note 1: If a soil will hold water 100 mm by capillarity acting against gravity, the soil will theoretically be able to hold the water only 0.1 mm against a centrifugal force that is 1000 times greater than the force of gravity. Note 2: The statements on precision and bias contained in this test method; the precision of this test method is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing. Users of this test method are cautioned that compliance with Practice D3740 does not in itself assure reliable testing. Reliable testing depends on many factors; Practice D3740 provides a means of evaluating some of these factors. 1.1 This test method covers the determination of the moisture equivalent of soil in the laboratory by means of a centrifuge technique. 1.2 This test method is limited to specimens of coarse-grained sandy soils having a maximum particle size of less than 2.00 mm and with fines of low plasticity. Soils having a unified soil classification, based upon procedures outlined in Practice D2488 such as SP, SW, SC-SM, or SM are considered acceptable for the test method. 1.2.1 For soils that are predominantly fine-grained, coarse-grained soils with medium to high plasticity, intact specimens or soils being tested at a specific density or unit weight refer to Test Methods D6836. 1.3 This test method is intended to be performed in ......

ASTM D2488-17 土壤描述和识别的标准实施规程(视觉-手动程序)

5.1 The descriptive information required in this practice can be used to describe a soil to aid in the evaluation of its significant properties for engineering use. 5.2 The descriptive information required in this practice should be used to supplement the classification of a soil as determined by Test Method D2487. 5.3 This practice may be used in identifying soils using the classification group symbols and names as prescribed in Test Method D2487. Since the names and symbols used in this practice to identify the soils are the same as those used in Test Method D2487, it shall be clearly stated in reports and all other appropriate documents, that the classification symbol and name are based on visual-manual procedures. 5.4 This practice is to be used for identification of soils in the field, laboratory, or any other location where soil samples are inspected and described. 5.5 This practice may be used to group similar soil samples to reduce the number of laboratory tests necessary for positive soil classification. Note 2: The ability to describe and identify soils correctly is learned more readily under the guidance of experienced personnel, but it may also be acquired systematically by comparing numerical laboratory test results for typical soils of each type with their visual and manual characteristics. 5.6 Soil samples from a given boring, test pit or location which appear to have similar characteristics are not required to follow all of the procedures in this practice, providing at least one sample is completely described and identified. These samples may follow only the necessary procedures to determine they are “similar” and shall be labeled as such. 5.7 This practice may be used in combination with Practice D4083 when working with frozen soils. Note 3: The quality of the result produced by this standard is dependent on the competence of the personnel performing it and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors. 1.1 This practice covers procedures for the description of soils for engineering purposes. 1.2 This practice also describes a procedure for id......
