In the later research, the interface friction coefficient (IFC) between reinforcements and soil should be considered in the formula to make it more perfect.doi:10.1007/978-3-540-69313-0_132L. R. XuCentral South UniversityD. W. LvCentral South University...
an algebraic rainfall-runoff model proposed by the SCS (USDA-SCS, 1972), is widely used to estimate the fraction of rainfall not retained in the soil (e.g., AnnGNPS). The simplicity of this formula encourages the use of CN method, though it can only be applied on a minimum daily time...
{\prime}\) is normal stress, \(tan\delta\) is interfacial friction coefficient, \(\delta\) is interfacial friction angle, \({f}_{c}\) and \({f}_{\varphi }\) are parameters that express the effect of the interface roughness change on cohesion and internal friction angle, respectively...

The output of a layer acts as input at nodes in subsequent layers whereas this procedure is iteratively repeated. The entire process is given in Fig.1whereas the pertaining formulae are expressed in Eqs. (3) and (4). The data is induced to the input layer after which the system weights...
Liquefaction is a phenomenon in which a saturated cohesionless soil loses its shear strength when subjected to vibratory ground motion during an earthquake. Shear strength in cohesionless soil is mainly imparted due to the friction produced between soil grains. Due to the significant increase in pore...
In the formula, μ is the friction factor, and p is the normal contact force between the two contact surfaces. 2.3. Unsaturated Soil Seepage and Strength 2.3.1. Unsaturated Seepage The flow of liquid pores into unsaturated soils follows Darcy’s law or Forchheimer’s law, and the expressions...
