PhiFlex: A Flexible Strategy for Estimating the Internal Friction Angle from SPT Test
This work proposes and analyzes a flexible model, named PhiFlex, for estimating the internal friction angle (φ) in granular soils based on the N60 value from Standard Penetration Tests (SPT). The model integrates and harmonizes various historical empirical formulas through a continuous interpolation between two branches (nonlinear and logarithmic ...openaire +1 more source

Investigation of Cohesion and Internal Friction Angle of Rock Materials by Indirect Methods
2015Kayaların makaslama dayanım parametreleri (kohezyon, c, ve içsel sürtünme açısı, ), kaya mühendisliği projelerinin tasarımında sıklıkla kullanılmaktadır. Ancak, bu parametrelerin belirlenmesi deneyim gerektiren, zahmetli ve pahalı bir işlemdir. Bu nedenle bu çalışmada, kaya malzemelerinin kohezyon ve içsel sürtünme açılarının pratik yönden tahmini ...
