It is significant to study the stability of surrounding rock in soft tunnels ensure construction safety and improve efficiency. Through triaxial shear tests on at various confining pressures, we observed failure characteristics transitioning from strain softening hardening as pressure increases. An improved Hoek-Brown strength criterion has been proposed characterize critical effect rock, with tensile zone aligning experimental results, showing an error less than 5%. By assuming that...
In this study, based on the background of massive freezing engineering in coastal strata, thermal physical parameters and some laws soil were obtained through tests frozen frost heaving tests. When temperatures −5°C, −10°C, −15°C, −20°C, rates 0.53%, 0.95%, 1.28%, 1.41%, forces 0.37 MPa, 0.46 0.59 0.74 respectively. range test conditions, rate force increased with decrease temperature, relationship was roughly linear temperature. The entire cooling process could be divided into three stages:...
