“…Figure 11 shows the failure envelope that originated from the crushing particle model of the bonding strength of 800 kPa. According to the results of the previous studies, the envelope changed to non-linear behavior in the case where the particle crushing occurred (Bolton, 1986;Feda, 2002). This study also showed that the failure envelope of the models which allowed particle crushing showed non-linearity compared with the non-crushing particle models, and consequently showed a considerable decrease of the internal friction angle.…”

“…shing is directly related to particle strength (Feda, 2002;Hardin, 1985;Lade et al, 1996;McDowell and Bolton, 1998 (Tsoungui et al, 1999;Lang, 2002). This study uses the second solution and a new simplified tensile failure criterion that can be easily implemented on DEM.…”

“…Moreover, other engineering properties such as the internal friction angle will change from their original values as crushing evolves. Previous researchers have found that granular materials undergoing crushing exhibit a non-linear failure envelope (Bishop, 1966;Miura and O-hara, 1979;Feda, 2002;Vallejo, 2003). However, recent ring shear tests on carbonate sand presented by Coop et al (2004) showed that the mobilized angle of shearing resistance does not considerably change regardless of the severe degradation of the tested material.…”

“…Moreover, on the issue of repeatability, studies by e.g., Feda (2002) and Hattamleh et al (2010) have reported changes in shear strength due to particle crushing, which initially was also of some concern in this study, especially due to the necessary reuse of samples. Yet, when retesting six of the samples, the results were either equal to, higher and lower than the ones obtained from the main test.…”

Shear strength of dry tills from the southern half of Norway in relation to bedrock geology

Till is the dominant Quaternary sediment in Norway, where the till deposits mostly originate from local rocks with a transport distance less than five kilometres. Debris slides and flows are among the main geohazards on till-covered valley slopes, and in this context the shear strength of Norwegian tills is poorly studied. Therefore, a set of 33 near-surface, genetically independent till samples were collected from various locations in the southern half of Norway to investigate the shear strength and its relation to bedrock geology. The disturbed samples were sieved (<16 mm) and dried before they were tested in a large-scale direct shear box apparatus at normal stresses of 100, 200 and 300 kPa, and with a shear rate of 2.0 mm/min for approximately 40.0 mm horizontal displacement. Overall, the result regarding the average 'initial dry testing density' was 1.67 g/cm 3 , while the maximum shear stresses for the given normal stresses on average were 84.9 kPa, 163.2 kPa and 243.7 kPa, respectively. The average angle of friction and cohesion were 38.4° and 5.3 kPa. Furthermore, the samples were categorised into six regional rock provinces. The mapped rock type assumed to represent the origin of the till samples were based on their area of extent around the sample sites, and adjusted for by the late-Weichselian ice-flow directions. On average, the 'Precambrian basement' province locally affected by the Caledonian orogeny (mainly gneisses) had the highest angle of friction. In comparison, the 'Caledonian' province of overthrust sheets of sandstone and schist (mainly sandstones) had the lowest angle of friction. Although not conclusive, this study provides indications of a relationship between till shear strength and bedrock geology, suggesting that some provinces may, solely on the basis of their associated geological parameters, be more prone to debris slides and flows than others.
