Stability Analysis on Tunnels With Karst Caves Using the Distinct Lattice Spring Model
Underground Space (China), 2021 The effects of karst caves on tunnel stability were numerically investigated using the distinct lattice spring model (DLSM). The DLSM was validated by investigating the mechanical behavior of Brazilian discs with various sizes of central circular holes ...

Observations on the habitat and feeding behaviour of the hypogean genus Eukoenenia (Palpigradi, Eukoeneniidae) in the Western Italian Alps [PDF]
Subterranean Biology, 2022 The order Palpigradi includes species characterized by millimetric size and a characteristic flagellum with bristles at the end of the opisthosoma. They represent one of the less well-known and obscure arachnid orders.

Identification of Karst Underground River Catchment Areas with Artificial Tracer Tests and Water Balance in Banteng Cave Springs (Karst Gombong Selatan, Central Java) [PDF]
E3S Web of Conferences, 2021 The karst hills of Gombong Selatan have abundant potential water resources, especially in locations that have underground springs and rivers. The connectivity between the subsurface passageways that is difficult to know can threaten the potential of ...

Seismic Response Analysis of Rock-Socketed Piles in Karst Areas under Vertical Loads
Applied Sciences, 2023 Karst landforms constitute one of the most harmful geological conditions, which have an adverse effect on the deep foundation structures of bridges. During earthquakes, the existence of karst caves can cause serious seismic damage to the bridge pile ...

Geoconservation initiatives for caves, karst, and springs
Parks Stewardship Forum, 2022 In this paper the focus is on the surface landforms that are found on carbonate karst, on caves within carbonate karst, and on the springs that discharge from carbonate karst.
