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%; these three groups of data are the most representative, representing ...

Abstract
The invention discloses a soil seepage-settlement test method, and aims to supplement and solve the problem of lack of existing soil seepage-settlement research. The test method comprises the steps ofS1, treatment of test soil; S2, treatment of test equipment; S3, filling of the test soil; S4, test data recording; and S5, treatment of test data, so that the seepage-settlement relation of a soil body is researched. According to the invention, the soil body settlement amount at any moment and the moisture content and density of the soil body at the corresponding moment can be measured, and therelationship between soil body seepage and settlement amount under different initial moisture content conditions is convenient to study; and according to the method, the defects existing in existing land seepage-settlement research are effectively overcome, a theoretical basis is provided for further researching the internal mechanism of land seepage-settlement and on-site construction, a guarantee is provided for on-site safe construction and safe production, and the method has very large 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...
