WebDiscussion of results In this case the joint fill material (a 2 mm thick layer of clay) resulted in a maximum post peak friction angle much lower than the basic friction angle of the rock. The basic friction angle is 36°. The measured maximum post-peak friction angle was tested as 17,0° and the WebJan 12, 2024 · The space between the wall and the rock mass was filled with fine sand. At the time of placing sand behind the wall, the wall lateral movements were prevented. The sand unit weight and internal angle of friction were equal to 15.8 kN/m 3 and 36º, respectively. The friction angle between the wall and the sand was equal to 25º.

WebMar 8, 2016 · The friction angle of tire chips from these tests ranged from 19° to 25°. Cohesion values range from 7.6 kPa (160 lb/ft 2) to 11.5 kPa (240 lb/ft 2), although significant deformation was required to develop cohesion. Tire chips with a greater amount of exposed steel belts tend to have a higher angle of internal friction. WebFeb 1, 2024 · Furthermore, the internal friction angle of the backfill soil is φ = 36 °, and the friction angles between the backfill soil and two retaining walls both equal δ. During … WebThe soil properties adopted for the probabilistic analysis using the random variable method are summarized in Table 2.Since the undrained condition is applied in this example, the undrained shear strength c u is modeled as a random variable for the clay layers while the friction angle φ is taken as a random variable for the sand layer.
