Comparison of Mechanical Properties and Sensitivity of Compressive and Flexural Strength of Artificial Frozen Sand

Some zones of freezing curtains subway contact channels are subjected to compression and tension. Thus, understanding the mechanical properties relationship between compressive flexural strengths frozen soil is crucial. In this regard, study considered sandy from Fuzhou as an example perform uniaxial three-point strength tests under different moisture content curing conditions. The results showed that were directly correlated with inversely temperature. Moreover, was significantly higher than strength, ratio 1.68 3.41. sensitivity analysis for two factors affecting performed using grey correlation method. a stronger effect on sand. contrast, temperature substantially affected strength. This provides reference optimizing scheme connection channels.
