Geophysical testing and slope stability analyses are used to confirm the location of the slide plane in ...

The article was presented the results of geophysical and geotechnical investigations and numerical simulations of the landslide in Brzozówka near Cracow. The creation of landslides (from the mechanical point of view) is associated with imbalances between forces which have a destructive impact on the soil and those forces which hold …

is dissolved by the action of groundwater (usually on limestone, dolomite, or marble), forming an area characterized by underground caves, fissures, and sinkholes, of which, cover-collapse sinkholes are the most prevalent (Fig. 1). Figure 1. Karst Terrain Diagram (Environmental Science Institute, 2012). Sinkholes are developed by two main ...

of geophysical investigation techniques. 3. To demonstrate the need for an effective reliable team to design, carry out and interpret geophysical investigations. REPORT STRUCTURE The report is structured to present a logical sequence through the process of using geophysics in site characterisation (Figure 1.1).

Some of the geophysical methods of explorations are electromagnetic profiling, ground-penetrating radar profiling, seismic methods, selfpotential methods, electrical resistivity tomography, etc [6 ...

A site located on the island of Brač is known in history for world-famous architectural stone and stone mining, dating all the way back to ancient Greek and Roman times. The most famous building …

Rock mass integrity is mainly assessed by geotechnical parameters. Rock quality designation (RQD) is a reliable geomechanical parameter, extensively used in geotechnical engineering to obtain proper design of large-scale engineering infrastructures. RQD is traditionally obtained by the rock cores from the boreholes. However, the …

Use this lesson plan for 11–14 year olds to help your students plan, implement and evaluate a practical investigation to determine if all limestone is the same. In this practical activity, students develop their …

In the present study, a new approach on the application of seismic methods for assessing the excavatability of sedimentary rocks for surface excavations is proposed. The excavatability classification system has been developed based on seismic S-waves velocities determined by the multichannel analysis of surface waves. Prior to practical …

Geophysical investigations can be beneficial in the mapping and identification of the subsurface geological and hydrogeological conditions. The application of electric methods for investigating fissured and karstic limestone aquifers is very effective (Parra et al., 2002; Fagerlund and Heinson, 2003; Skinner and Heinson, 2004; Boadu et …

It further confirmed that both semi-airborne receiver instruments achieve the band-width and sensitivity required for the investigation of the resistivity structure …

A site located on the island of Brač is known in history for world-famous architectural stone and stone mining, dating all the way back to ancient Greek and Roman times. The most famous building constructed from the stone from Brač is the Diocletian Cesar Palace in the town Split. Prospective new locations for quarries are still required …

A magnetic geophysical survey to delineate the karstic structure of the Nyanda Mountains, Masvingo, was carried out in the interest of mapping out limestone deposits required for cement production. The magnetic-total-field-anomaly maps helped reveal the metamorphic and sedimentary units in the study area.

We describe the use of GPR to detect voids within a limestone outcrop, as an aid to locating cave systems which might contain sediments suitable for excavation. The …

Electrical methods of geophysical prospecting are the most important methods for groundwater investigation as they are the best method to detect the existence between electrical properties ...

Thus, an integrated geophysical investigation, including magnetic, 2D resistivity, VLF-R and seismic methods, were carried out in the area. Magnetic data were collected using gradient measuring ...

Cross section A-A′ in Fig. 2 indicates that the levee is underlain by a clay-rich overburden averaging 3 m thick (Fig. 4).Below the clay overburden, the sediment coarsens into silt, and eventually a thick sand unit, which is assigned to the permeable substratum (Brackett 2012).Similar cross section is observed on the waterside of the levee with sand …
