“…SPT serves as a cost-effective geotechnical and geoengineering testing technique commonly employed in infrastructure design (Bery and Saad, 2012;Syukri, 2020;Al-Heety et al, 2021). While traditionally utilized for engineering site assessments, SPT results also offer valuable insights for groundwater exploration.…”

“…Standardized statistical analyses of geotechnical parameters (RQD and N-values) with velocity and resistivity data can effectively yield the required results (Sivrikaya and Toğrol, 2006;Priya and Dodagoudar, 2015;Kumar et al, 2016). Such estimates and derivations are crucial in infrastructure design, groundwater exploration, and soil/rock excavation to predict associated physical, geomechanical, and hydrogeological properties in areas with limited borehole information (Sivrikaya and Toğrol, 2006;Kalantary et al, 2009;Al-Heety et al, 2021;. Additionally, detailed characterization of soil-rock profiles and their interfaces can provide two-and three-dimensional (2-D and 3-D) variability images of the near-surface, essential for mitigating risks like slope failure, soil liquefaction, and ground subsidence (Kalantary et al, 2009;Priya and Dodagoudar, 2015;Sujitapan et al, 2024).…”

Surface–subsurface soil-rock modeling is crucial for infrastructure design and groundwater yield optimization, especially in the complex crystalline basement terrains of Penang Island, Malaysia. This study conducted large-scale characterization of soil-rock profiles using ERT, SRT, rock quality designation, and soil penetration test (SPT N-values) data, optimized through regression modeling. The approach effectively identified soil-rock structures and their suitability to prevent structural failures and enhance groundwater productivity. Correlations between borehole lithologic logs and velocity–resistivity models revealed distinct soil compositions across the study area. The results highlighted thick, saturated, and loose silty to sandy bodies in the eastern to northern sections, contrasting with sandy compositions and penetrative fractures in the southern part. The study also found good correlations between rock mass quality and N-values for different soil types. Depths of intra-bedrock weathered/fractured units varied between 12 and >35 m. This has significant implications for determining optimal foundation depths in the study area. Groundwater productivity was associated with intra-bedrock planes of weakness at depths exceeding 40 m. Overall, this study developed empirical relations between geophysical and geotechnical parameters for wet tropical granitic terrains, filling critical gaps in understanding subsurface characteristics.

Natural disasters such as debris flow caused by earthquakes seriously threaten the local infrastructure and economy, as well as the lives of people in the area. As the material source of debris flow, it has significance to accurately and effectively study the underground structure of the landslide to prevent debris flow disasters. A landslide has a complex structural system, and its underground characteristics play an important role in its stability. The early identification of fracture surfaces and unstable bodies, and assessment of potential hazards are essential for prevention and protection. The research object of this paper is a landslide that occurred in Yige Village, Xianshui Town, Daofu County, which is on the Xianshui River Earthquake Zone, an area subject to frequent earthquakes. In western Sichuan, the frequent occurrence of landslides has caused considerable economic losses. Developing methods for efficient and accurate risk assessment is a top priority. The Daofu landslide is a typical example of a landslide directly threatening the road below and forming a debris flow channel. The lithology is composed of Jurassic sedimentary rocks, such as marl and clay, covered by limestone. In this study, we combined traditional methods (drilling and field investigation) with two geophysical techniques, multichannel analysis of surface waves (MASW) and electrical resistivity tomography (ERT) to effectively determine the electrical characteristics, velocity characteristics and spatial structure of the landslide. It is found that the buried depth of the sliding surface of the landslide is about 16–20 m. The sliding body above the sliding surface forms a low velocity and low resistivity Quaternary cover. The rock mass below the sliding surface is Triassic Zhuwo Formation sandstone and slate with high velocity and high resistivity. According to comprehensive analysis, the landslide lacks sufficient stability under rainstorm. Our study shows that the use of MASW and ERT can quickly and effectively characterize the subsurface of landslides to assess landslide risk and prevent debris flow hazards.

“…It is important as an engineer to determine and predict whether the surface and the subsurface of a proposed construction site are safe and suitable to yield the total designated weight of a structure over a prolonged period. To estimate the strength and safety of the site, geotechnical properties are important parameters to be investigated in civil construction and design, monitoring, maintenance or rehabilitation purposes during the pre and post construction (Al-Heety et al, 2021;Ungureanu et al, 2017) . It is important to investigate and predict the condition of the subsurface that may affect the long-term safety of the structures such as salt-water intrusions, underground voids, and groundwater movements to avoid accidents and major losses to the structures (Helaly, 2017;Xiao et al, 2021;Zhao & Konietzky, 2020).…”

Electrical resistivity tomography is a non-destructive method of site investigation that involvesinjecting electricity into the sample and measuring subsurface resistance. This study looked at the effects of compaction on resistivity values as well as the relationship between different degrees of compaction. The material used in this experiment was laterite soil. The sample was tested into a standard proctor mould. The model has 10.20cm diameter and 11.6 cm for height of the mould. Each sample's resistivity was measured entirely compacted.The resistivity testing in this study were conducted using the Miller 400A. ASTM D 422 Standards were used, and for electrical resistivity testing, ASTM G57 is used. This research emphasises the impact of moisture content on resistivity value, as soil reduces resistivity value when the soil has higher moisture content which is 120 Ωm at 37%, and 190 Ωm at 25%. By comparing the results of different moisture content of soil samples under varied degrees of compaction, better resistivity interpretation tables may be generated.
