The percentage of quartz in the siltstone decreased from 91 to 82%, and kaolinite decreased from 6 to 1%.

Using groundwater dynamics and Bernoulli's energy equation, a theoretical approach to calculate the tunnel face water inrush under non-Darcy flow conditions was proposed, which comprised a confined water formula and a phreatic water formula. This methodology considers temporal and geological variations to enable short-, medium-, and long-term dynamic predictions of water inflow. The research findings indicate that: for short-term predictions, the theoretical water inflow derived from both formulas exhibited at most 5% deviations from the actual measurements. When a 90% confidence interval was adopted for the medium-to-long-term predictions, the relative errors for both maximum and normal water inflow remained below 5%. Notably, during the decaying water inrush phase, the phreatic water formula predicted a 2–3 times slower decay rate than the confined water formula. The maximum water inflow positively correlates with the permeability coefficient (<i>K</i>), water head height (<i>H</i>), and diameter of the water inrush channel (<i>d</i>), whereas it negatively correlates with the length of the water inrush channel (<i>L</i>). Conversely, the normal water inflow negatively correlates with <i>K</i> and <i>d</i> but positively correlates with <i>H</i> and <i>L</i>.

To study the low-temperature properties of loess and red clay strata, loess-red clay composite samples with varying water contents were subjected to freezing at different low temperatures. Their resistivity and P-wave velocity were measured postfreezing. The results indicate that as water content increases, soil resistivity decreases due to enhanced electrical conduction, with a slower rate of decline. When the temperature decreases, resistivity rises gradually in the unfrozen stage (25 °C to − 5 °C) and increases rapidly in the frozen stage (–10 °C to − 20 °C) as water transitions to solid ice. At low water contents, soil resistivity is more sensitive to temperature changes due to reduced liquid conductive pathways. P-wave velocity decreases almost linearly with increasing water content in unfrozen soils, but this trend reverses in frozen soils. With decreasing temperature, P-wave velocity shows minimal change in unfrozen soils but increases significantly after freezing, with greater sensitivity to temperature changes at higher water contents.

In this study, a reconstituted soil is reconstituted to simulate the soil with high liquid limit from the site of the reconstruction and expansion project for the Zhangshu-Ji’an Highway in Jiangxi, China. This reconstituted soil was reinforced using steel slag, varying in grain sizes and employing two mixing methods. The mechanical characteristics of the pure and reinforced soil were examined by a series of monotonic and cyclic triaxial tests. The results indicate that decreasing the grain size of steel slag increases the monotonic shear strength and leads to a decrease in the permanent strain under cyclic loading, regardless of the mixing methods. The reduction in grain size of steel slag increases the total frictional surface area, thereby enhancing soil strength and resistance to deformation. Compared to the samples by uniform mixing with the steel slag, the samples by layered mixing results in a greater shear strength and a more significant permanent strain, because the concentrated steel slag grains and reconstituted soil particles produce greater friction and more significant compressibility, respectively. Overall, smaller grains of the steel slag by uniform mixing are more effective for reinforcing weak soil with high liquid limit, as it provides a higher monotonic strength and a lower permanent deformation, and reduces rapid energy dissipation under cyclic loading, compared to layered mixing.</p>","PeriodicalId":500,"journal":{"name":"Bulletin of Engineering Geology and the Environment","volume":"84 3","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast to conventional split Hopkinson pressure bar (SHPB) systems, this research employed a custom-designed electromagnetic pendulum impact testing (EPIT) system. The electromagnetically controlled EPIT system was developed to allow precise and consistent repetition of impact tests at varied speeds. The EPIT system was integrated into a modified SHPB apparatus, featuring an extended length of up to 3 m and using rock bars exclusively, rather than conventional steel bars. Three types of modified SHPB configurations-single-rock-bar, double-rock-bar, and triple-rock-bar systems-were analyzed. Testing was conducted on limestone, marble, and sandstone specimens, each measuring 1 m in length and 0.05 m in diameter. Results indicate that sandstone exhibits the highest peak compressive strain and attenuation rate along the propagation path, distinguishing it from the behaviors observed in limestone and marble.

The mechanical properties, energy dissipation characteristics, and crack extension evolution process of oil-saturated sandstone were obtained. The results show that the softening coefficient of oil-saturated sandstone has a change rule of increasing and then decreasing with the increase of confining pressure. The oil-saturated treatment does not change the energy evolution process of the sandstone, but it has a greater influence on the energy parameters. The number of AE events and the released energy of oil-saturated sandstone is lower than that of natural sandstone at different confining pressures. However, due to the influence of the Kaiser Effect, the difference gradually decreases with the increase of the confining pressure, which macroscopically shows that the increase of the confining pressure moderates the effect of oil saturation on the energy parameters and crack extension of sandstone.
