Embodiment Construction
[0042] The present invention will be further described below in combination with specific examples. The test basis of this test is: "Standards for Soil Test Methods" (GBT 50123-2019); "Highway Soil Test Regulations" (JTG E40-2007).
[0043] A soil seepage-settlement test method, such as figure 1 shown, including the following steps:
[0044] S1. Test soil treatment: collect test soil and put it in a sealed box for sealed storage. Divide the test soil into 3 equal parts in the laboratory, select part of the test soil to measure the initial moisture content by drying method, add water to the test soil according to the initial moisture content and seal the stuffy soil, control the stuffing time for 20 to 30 hours, After the soil, continue to measure the moisture content, and so on and forth, and finally control the moisture content of the three groups of test soils to be 23% to 27%, 28% to 32%, and 33% to 37% respectively; these three groups of data are the most representative, ...

Abstract
The invention discloses a test method for soil seepage-settlement, aiming at supplementing and solving the problem of lack in the existing study of soil seepage-settlement. The test method includes S1. Test soil treatment, S2. Test equipment treatment, S3. Test soil filling, S4. Test data recording, S5. Test data processing steps, to study the seepage-settlement relationship of the soil. The invention can measure the soil settlement at any time and the moisture content and density of the soil at the corresponding time, which is convenient for studying the relationship between soil seepage and settlement under different initial moisture content conditions; the method effectively supplements the existing land The deficiencies in the study of seepage-subsidence provide a theoretical basis for further research on the internal mechanism of land seepage-subsidence, as well as provide a theoretical basis for on-site construction, and provide guarantees for safe construction and production on site. It has great application prospects and social value.
Description
technical field [0001] The invention belongs to the technical field of soil seepage and settlement, and in particular relates to a test method for soil seepage and settlement. Background technique [0002] Normally, soil is a three-phase system composed of solid (soil particles, etc.), liquid (water) and gas. The volume of soil shrinks under the action of external pressure. This characteristic is called the compressibility of soil. The compressibility of soil is usually divided into: ①The solid particles of the soil are compressed; ②The water and gas in the soil are compressed; ③The water and gas are discharged from the voids, and the soil is compressed. Tests have shown that the compression of solid particles and water is very small and negligible. Therefore, the compression of the soil is mainly the water and air in the pores are discharged, and the relative displacement, rearrangement, and compaction of the soil particles cause the soil to compress and deform. This proce...
