Description

Technical Field

[0001] This invention relates to the field of long-term strength calculation technology for solidified soil, and in particular to a method and system for calculating the strength of solidified soil that takes into account the number of freeze-thaw cycles and the burial depth. Background Technology

[0002] Solidified soil technology is widely used in geotechnical engineering fields such as roadbed engineering, foundation treatment, and foundation pit support in seasonally frozen soil regions of my country due to its advantages such as good economy, environmental friendliness, and convenient construction. The natural environment of seasonally frozen soil regions causes solidified soil to undergo repeated freeze-thaw cycles during long-term service. Frequent phase changes and migrations of water within the soil gradually lead to phenomena such as microcrack propagation, cementation damage, and pore structure deterioration in the internal structure of the solidified soil. This results in a continuous decrease in the strength and deformation modulus of the solidified soil, which directly affects the long-term load-bearing safety and deformation stability of engineering structures.

[0003] Most existing methods do not fully consider the strength degradation effect of freeze-thaw cycles on solidified soil, and fail to incorporate the strength and modulus attenuation caused by freeze-thaw cycles into the strength calculation system. This results in significant deviations between the calculated results and the actual stress and degradation state in engineering sites, which can easily lead to unsafe designs and create potential safety hazards for engineering structures. Furthermore, most existing studies only analyze single factors such as the number of freeze-thaw cycles, freeze-thaw temperature, and confining pressure, failing to consider the coupling of multiple factors including burial depth, number of freeze-thaw cycles, freeze-thaw temperature, and stress state. This does not match the actual working conditions of soil constraint factors in real engineering projects, resulting in limited applicability and low prediction accuracy of the calculation models, making them difficult to directly apply to the long-term strength and deformation calculation of solidified soil foundations in seasonally frozen areas.

[0025] Example 1 like Figure 1 As shown, this embodiment provides a method for calculating the strength of solidified soil considering the number of freeze-thaw cycles and burial depth, including: To obtain the strength and modulus of solidified soil under different freeze-thaw cycles and different burial depths; The strength reduction factor is obtained by comparing the strength after different freeze-thaw cycles with the strength without freeze-thaw cycles; the modulus reduction factor is obtained by comparing the modulus after different freeze-thaw cycles with the modulus without freeze-thaw cycles. Based on the relationship between different freeze-thaw cycles, different burial depths, and the strength reduction coefficient and modulus reduction coefficient of solidified soil, a composite exponential function model of the strength reduction coefficient and modulus reduction coefficient is constructed; the inputs of the composite exponential function model are the freeze-thaw confining pressure, consolidation confining pressure, freeze-thaw temperature, and number of freeze-thaw cycles corresponding to the burial depth.

[0026] The specific steps are as follows: S1: Obtain the strength and modulus of solidified soil under different freeze-thaw cycles and different burial depths; The strength reduction factor is obtained by comparing the strength after different freeze-thaw cycles with the strength without freeze-thaw cycles; the modulus reduction factor is obtained by comparing the modulus after different freeze-thaw cycles with the modulus without freeze-thaw cycles, specifically including: S11: Obtain the strength and modulus of solidified soil under different freeze-thaw cycles and different burial depths; A parameter m, which comprehensively reflects the effects of burial depth, number of freeze-thaw cycles, and freezing temperature, is defined by the following formula: (1) in This indicates the freeze-thaw confining pressure corresponding to the burial depth H; The consolidation pressure is represented by T; the freeze-thaw temperature is represented by n; and the number of freeze-thaw cycles is represented by n.

[0027] This embodiment obtains the strength and modulus at different freeze-thaw cycles and different burial depths based on indoor unconfined compressive strength test data, such as... Figure 2 and Figure 3 As shown, the parameters m and the strength and modulus under different freeze-thaw cycles are obtained.

[0028] S12: The strength reduction factor is obtained by comparing the strength after different freeze-thaw cycles with the strength without freeze-thaw cycles. The formula is as follows: (2) in, This indicates the strength after n freeze-thaw cycles. It indicates the strength without freezing and thawing.

[0029] S13: Based on the ratio of the modulus after different freeze-thaw cycles to the modulus without freeze-thaw cycles, the modulus reduction factor is obtained, expressed by the formula: (3) in, This represents the modulus after n freeze-thaw cycles. This indicates the modulus without freeze-thaw cycles.

[0030] S2: Based on the relationship between different freeze-thaw cycle numbers, different burial depths, and the strength reduction coefficient and modulus reduction coefficient of solidified soil, a composite exponential function model of the strength reduction coefficient and modulus reduction coefficient is constructed; the inputs of the composite exponential function model are the freeze-thaw confining pressure, consolidation confining pressure, freeze-thaw temperature, and freeze-thaw cycle number corresponding to the burial depth, specifically including: according to Figure 2 and Figure 3 The data in the formula function Construct an exponential function model for the intensity reduction coefficient, and combine m and K. q Substitute the formula function and obtain the formula coefficients through regression analysis. y 0, α 1, α 2, β 1, β 2. Substitute into the formula function ,get: (4) Similarly, using formulas and functions Constructing an exponential function model of the modulus reduction factor, we obtain: (5) Therefore, the composite exponential function model of the strength reduction factor and the modulus reduction factor is: (6) S3: Obtain the freeze-thaw confining pressure, consolidation confining pressure, freeze-thaw temperature, and number of freeze-thaw cycles in the actual project, and obtain the corresponding strength reduction factor and modulus reduction factor of the solidified soil under the actual project. S4: Based on the strength reduction factor and modulus reduction factor of the solidified soil under the actual engineering, the strength and modulus under different freeze-thaw cycles and different burial depths are obtained under the actual engineering. S5: Assess the safety of the project based on the number of freeze-thaw cycles, strength and modulus at different burial depths in actual engineering projects.

[0031] In one embodiment, the safety of an engineering project is assessed based on the strength and modulus of the solidified soil under different depths and freeze-thaw cycles. Specifically, the strength and modulus of the solidified soil at different burial depths and different numbers of freeze-thaw cycles can be used to calculate the long-term strength and deformation of the foundation.

[0032] In one embodiment, the strength and modulus of the solidified soil at a depth of 1m after undergoing 10 freeze-thaw cycles were evaluated, wherein the freezing temperature was -10°C, the strength of the solidified soil was obtained as 300 kPa according to the unconfined compressive strength test, and the compressive modulus of the solidified soil was obtained as 60 MPa through the consolidation test.

[0033] The density of the solidified soil at a depth of 1m was obtained using the conventional ring cutter method. Considering an additional stress of 100 kPa over a large area, the vertical stress at this point is 1.6 × 10 × 1000 = 16 kPa, and the freeze-thaw confining pressure... and consolidation pressure Both are 16+100=116kPa. After freezing at -10°C and 10 freeze-thaw cycles, the parameter m can be calculated using formula (1): .

[0034] Then, the strength reduction factor and the modulus reduction factor are calculated according to formula (6):

[0035] Subsequently, based on the concepts of strength reduction factor and modulus reduction factor, the strength and modulus of the solidified soil at a depth of 1m after freezing at -10°C and 10 freeze-thaw cycles are calculated as follows:

[0036]

[0037] In one embodiment, the foundation bearing capacity is assessed based on the strength and modulus of the solidified soil at a depth of 1m after 10 freeze-thaw cycles: Soil cohesion If the unconfined compressive strength is half of the unconfined compressive strength, then for a strip foundation, the ultimate bearing capacity of the solidified soil foundation calculated using Terzaghi's formula is 5.14. Before the freeze-thaw cycle, the bearing capacity of the foundation is 300×0.5×5.14=771kPa. After 10 freeze-thaw cycles, the bearing capacity of the foundation is 175.65×0.5×5.14=451.42kPa.

[0038] In one embodiment, deformation is assessed based on the strength and modulus of the solidified soil at a depth of 1m after 10 freeze-thaw cycles: the deformation s can be calculated using the following formula: (7) in, The additional stress is 100 kPa in this embodiment. The value represents the compressibility modulus of the solidified soil under different freeze-thaw cycles, and H represents the thickness of the solidified soil, which is 1m in this embodiment.

[0039] Before the freeze-thaw cycle, the foundation deformation is: s = 100 * 1 / (60 * 1000) = 1.67 mm After 10 freeze-thaw cycles, the foundation deformation is: s = 100 * 1 / (27.73 * 1000) = 3.61 mm.

[0040] Based on the actual engineering conditions, the compressive strength and deformation modulus of the solidified soil corresponding to different freeze-thaw cycles and different burial depths are calculated for both the ultimate limit state and the serviceability limit state. Bearing capacity safety assessment: Substitute the reduced strength of the solidified soil into the formula for calculating the ultimate bearing capacity of the foundation to obtain the ultimate bearing capacity after freeze-thaw degradation; determine whether it meets the engineering requirements according to relevant specifications.

[0041] Deformation safety judgment: The foundation settlement deformation value is calculated using the reduced deformation modulus; if the calculated deformation value is not greater than the design allowable deformation limit required by the relevant specifications, it is judged to meet the deformation requirements.

[0042] Overall safety assessment: When the solidified soil meets both the bearing capacity and deformation requirements, the structure of the project is deemed to meet the design requirements and be structurally safe. If any one of the indicators fails to meet the requirements, the mix proportion of the solidified soil, the burial depth, or anti-freeze-thaw reinforcement measures must be adjusted, and the calculation must be repeated until the safety conditions are met.

Strength and Modulus Calculation Module: Based on the relationship between different freeze-thaw cycles, different burial depths, and the strength reduction coefficient and modulus reduction coefficient of solidified soil, a composite exponential function model of the strength reduction coefficient and modulus reduction coefficient is constructed; the inputs of the composite exponential function model are the freeze-thaw confining pressure, consolidation confining pressure, freeze-thaw temperature, and number of freeze-thaw cycles corresponding to the burial depth; Obtain the freeze-thaw confining pressure, consolidation confining pressure, freeze-thaw temperature, and number of freeze-thaw cycles in actual engineering projects, and obtain the corresponding strength reduction factor and modulus reduction factor of the solidified soil under actual engineering conditions.
