Description

Technical Field

[0001] This invention relates to the field of geotechnical engineering technology, and in particular to a consolidation test system and method for monitoring water-gas separation. Background Technology

[0002] Millimeter-level settlement control of high-speed railway subgrade is a key technology for ensuring the high-speed, stable, and safe operation of trains. The TB10077—2019 "Standard for Classification of Geotechnical Materials for Railway Engineering" defines a compression coefficient of 0.1–0.3 MPa as... -1 Soil is defined as medium to low compressibility. Numerous studies have shown that the compressibility coefficient ranges from 0.1 to 0.3 MPa. -1 The foundation soil exhibits rapid deformation convergence, and can be used as the bearing layer for high-speed railway subgrade structures after only certain technical treatments. However, the deformation mechanism by which medium-to-low compressibility soils achieve rapid settlement convergence as high-speed railway foundations remains unknown.

[0003] The purpose of consolidation tests is to determine the settlement and deformation of high-speed railway foundation soil, understand the relationship between soil deformation and time-pressure under lateral confinement conditions, simulate the load changes experienced by the soil in actual engineering projects, further study the consolidation properties of the soil, provide essential calculation parameters for estimating the settlement of high-speed railway foundations and the degree of consolidation over different times, and reveal the deformation mechanism of high-speed railway foundations. Due to the presence of gas in the soil pores, the consolidation process of high-speed railway foundation soil becomes more complex, and the influence of gas on the soil compression consolidation process cannot be ignored. Currently, most existing studies only consider the theoretical research on water phase flow in the soil and one-dimensional consolidation calculations. Meanwhile, the testing functions of existing consolidation instruments are mainly focused on monitoring the vertical deformation of the soil and the drainage of moisture inside the specimen, ignoring the gas phase flow inside the specimen. That is, they cannot measure the changes in gas inside the soil pores, thus they cannot comprehensively analyze and evaluate the changes in pore compression during the consolidation process of high-speed railway foundation soil, nor can they calculate compression and consolidation coefficients that take into account water and gas changes and are more in line with reality. Consequently, they cannot reveal the deformation mechanism of rapid settlement convergence of medium and low compressibility soil in high-speed railway foundations and accurately predict settlement. Summary of the Invention

[0004] To address unresolved engineering challenges and shortcomings of existing technologies, the present invention aims to provide a consolidation test system and method for monitoring water-air separation. This system effectively monitors water-air separation during the consolidation process. By considering drainage and air release phenomena during consolidation deformation, and further calculating the compression coefficient and consolidation coefficient, the system can more comprehensively and effectively analyze the compression and consolidation characteristics of soil. This is of crucial significance for the accurate prediction of subsequent foundation settlement and for revealing the deformation mechanism of rapid convergence of settlement in medium- and low-compressibility soil high-speed railway foundations.

[0052] Example 2

[0053] This embodiment provides a consolidation test method for water-gas separation monitoring, including:

[0054] Before the experiment began, the pressure chamber 9 was filled with water, and the air compressor 27 was used as the air source. The pressure was set to 300 kPa to saturate the first high air intake value clay plate 4 and the second high air intake value clay plate 13.

[0055] Prepare the test specimens required for the test, place the specimens in the pressure chamber 9, and make the specimens fit tightly against the inner wall of the pressure chamber. Fix the tension gauge 8 on one side of the specimens so that the tension gauge 8 fits tightly against the specimens.

[0056] During the matrix suction stabilization process, close the first valve 15, the high-precision gas flow monitoring valve 16, the second valve 19, and the third valve 20. Start the air compressor 27, using it as the air source. Adjust the air pressure regulating valve 25 to set the target air pressure value. It is recommended that this air pressure value be consistent with the matrix suction value corresponding to the initial moisture content of the specimen. After the pressure output stabilizes, open the second valve 19, the first valve 15, and the third valve 20 to provide matrix suction to the specimen. Observe the changes in the readings of the first high-precision electronic balance 22 and the second high-precision electronic balance 23. When the change in reading is less than 0.01g within 2 hours, the specimen is considered to have reached a stable state at this suction level.

[0057] During the consolidation test, valves 15, 19, and 20 are closed. Axial pressure sensor 1 applies the target axial pressure to the specimen. Then, valves 15, 16, and 20 are opened. The ultra-clean pore pressure generated instantaneously during axial pressure application gradually dissipates, and pore gas and water inside the specimen begin to escape. The gas flow rate can be observed in real-time on display screen 17.

Each level of axial pressure is applied and recorded for 24 hours, and the above steps are repeated for the next level of axial pressure application.

[0058] Calculate the compressibility and consolidation coefficient;

[0059] The compression of soil pores consists of two parts: gas compression and water compression.

[0060]

[0061] Further simplified to

[0062]

[0063] Where: M aw V is the soil compression coefficient; w V is the volume of water drained from the pores. a μ is the volume of exhaust gas in the pores. w The ultra-clean pore water pressure measured by a gas pressure sensor; μ a The pore pressure is the clean pore air pressure measured by the pore pressure sensor; P is the standard atmospheric pressure; S r σ represents the soil saturation; σ is the applied axial pressure.

[0064] The formula for calculating the consolidation coefficient is as follows:

[0065]

[0066]

[0067] In the formula: C v γ is the consolidation coefficient of the soil; e is the void ratio; γ w is the unit weight of water; k is a function of the permeability coefficient, and the corresponding function for the test soil needs to be obtained through permeability testing; K c θ is the permeability coefficient of the soil used in the test; g The exhaust volume is measured by a high-precision gas flow monitoring valve; b, c, and n are fitting parameters.

[0068] The compressibility coefficient describes the compressibility of soil under pressure and is an important indicator of soil compressibility. The consolidation coefficient reflects the rate of soil consolidation and the consolidation characteristics of soil layers, and is an important soil testing indicator. The effective and accurate acquisition of the consolidation coefficient is crucial for the accurate prediction of foundation settlement.

Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
