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...
Figure13shows a Taylor diagram for both the training and test datasets. This visual representation was designed to illustrate the overall performance of the models, considering factors such as the correlation coefficient (R), standard deviation (SD), and RMSE values. The observations in the Taylor ...
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...
which employed a helical ground anchor for counterforce and featured an automatic balance adjustment device. The investigation utilized double-bridge static probing equipment, developed domestically in China. The equipment’s probe had a tip cross-sectional area of 15cm2, while the side friction sleeve...

According to ANOVA results, the interaction terms of sandy soil-sandy soil static friction coefficient and sandy soil-steel static friction coefficient and the interaction term of sandy soil-sandy soil static friction coefficient and sandy soil-steel restitution coefficient had crucial impacts. Utilize ...
It can be calculated by the empirical formula (Shao et al., 1997): λ = ⎧0 ⎨⎩−0.35ln(1 − f ) f f = < 11. (4) In the centre of Taklimakan Desert, vegetation is sparse and has a simple community structure. Except for the oilfield operation area, living area and ...
(1) neglects the influence of friction resistance between soil particles when calculating the critical hydraulic gradient [26], while the critical hydraulic gradient of cohesive soil foundation is bound up with its shear strength, and therefore, this formula falls into a failure to solve the ...
This can be achieved by using a stack of aluminum rings supported individually with bearings, which permit a relative movement between the rings with minimal friction. Several studies have confirmed that the laminar container is compatible with the large soil deformation expected during the simulation ...
{\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...
