“…Experimental studies include mostly plane strain model tests on a strip trapdoor under normal earth's gravity i.e. 1g tests (Engesser, 1882;Terzaghi, 1936;McNulty, 1965;Ladanyi and Hoyaux, 1969;Evan, 1983;Tanaka and Sakai, 1993) and centrifuge tests under elevated acceleration levels (Stone and Wood, 1988;Craig, 1990;Iglesia, 1991;Abdulla and Goodings, 1994). Theoretical studies include solutions based on theory of elasticity (Finn, 1963;Chelapati, 1964), limit analysis (Davis, 1968;Gunn, 1980;Evan, 1983;Sloan et al, 1990; Singh and Basudhar, 1995; Smith, 1998), limit equilibrium (Engesser, 1882;Bierbaumer, 1913;Terzaghi, 1943;Krynine, 1945;Vardoulakis et al, 1981), andˆnite element analysis (Koutsabeloulis and Gri‹ths, 1989;Tanaka and Sakai, 1993;Nakai, et al, 1995).…”

“…In the past, some models were implemented using different approaches such as centrifuge models, analogical models, and actual soil physical models (Abdulla and Goodings, 1996) (Goodings and Abdulla, 2002) (Chen and Beck, 1989) (Caudron et al, 2006a(Caudron et al, , 2006b) (Caudron et al, 2008) (Lei et al, 1994) (Lei et al, 2005).…”

“…Gravimetric methods are suitable for the detection of cavities and mass movement (Arzi, 1975;Neumann, 1977;Butler, 1984;Benson et al, 1995), but they also deliver information about possible cavity fills, as do geoelectric (Militzer et al, 1979;Bataynek and Al-Zoubi, 2000;Miensopust et al, 2015) and geomagnetic (Bosch and Müller, 2001) methods. Analogue and digital mechanical modeling of the development and the propagation of collapse sinkholes is also a valuable tool (Abdulla and Goodings, 1996;Tharp, 1999;Augarde et al, 2003). Seismic (Steeples et al, 1986;Bolger et al, 1995;Shtivelman et al, 2002;Krawczyk et al, 2012) and groundpenetrating radar (GPR) (Kaspar and Pecen, 1975;Ulriksen, 1982;Forkmann, 1997;Batayneh et al, 2002) can deliver an image of the underground and provide physical attributes.…”

High-resolution shear-wave seismic reflection as a tool to image near-surface subrosion structures – a case study in Bad Frankenhausen, Germany

Abstract. Subrosion is the subsurface leaching of soluble rocks that results in the formation of depression and collapse structures. This global phenomenon is a geohazard in urban areas. To study near-surface subrosion structures, four shear-wave seismic reflection profiles, with a total length of ca. 332 m, were carried out around the famous leaning church tower of Bad Frankenhausen in northern Thuringia, Germany, which shows an inclination of 4.93 • from the vertical. Most of the geological underground of Thuringia is characterized by soluble Permian deposits, and the Kyffhäuser Southern Margin Fault is assumed to be a main pathway for water to leach the evaporite. The seismic profiles were acquired with the horizontal micro-vibrator ELVIS, developed at Leibniz Institute for Applied Geophysics (LIAG), and a 72 m long landstreamer equipped with 72 horizontal geophones. The high-resolution seismic sections show subrosion-induced structures to a depth of ca. 100 m and reveal five features associated with the leaching of Permian deposits: (1) lateral and vertical varying reflection patterns caused by strongly heterogeneous strata, (2) discontinuous reflectors, small offsets, and faults, which show the underground is heavily fractured, (3) formation of depression structures in the near-surface, (4) diffractions in the unmigrated seismic sections that indicate increased scattering of the seismic waves, and (5) varying seismic velocities and low-velocity zones that are presumably caused by fractures and upward-migrating cavities. A previously undiscovered southward-dipping listric normal fault was also found, to the north of the church. It probably serves as a pathway for water to leach the Permian formations below the church and causes the tilting of the church tower. This case study shows the potential of horizontal shear-wave seismic reflection to image near-surface subrosion structures in an urban environment with a horizontal resolution of less than 1 m in the uppermost 10-15 m.
