Schematic overview of the horizontal extended well

Reference: Theory and Practice of Pile Foundations The first approach considered the 'N60' of the SPT values. While, the second considered 'N' value with the effective stress value.

The Support at D allows Horizontal Translation only and Prevents Rotation and Vertical Translation. The Support D settles down 40 mm. What could be the slope deflection equation for member CD? Using Slope Deflection Method of Structural Analysis. Your Thoughts?

The use of auger cast piles forms the deep foundation system that ensures stability and durability. In this blog post, we explore the process of installing auger cast piles and preparing form boards, crucial steps in the foundation phase of our project. https://lnkd.in/eYi68eZZ

Darcy-Brinkman Flow Through a Slider Bearing with Surface Roughnesses. Abstract A double perturbation analysis is performed to the Darcy–Brinkman equations for a two-dimensional slider bearing with homogeneous surface roughness. The surface roughness is parallel to the flow direction. The stationary random model is used to mimic the surface roughness of the slider bearing walls. The slider is filled with a porous medium. The effect of the corrugations on the average load capacity is examined as a function of wave length and the permeability of the slider bearing. The limiting cases of Stokes and Darcy’s flows are discussed. ==================================== Volume100, Issue10 October 2020 e201900287

Last of my mini post-frenzy on discrete element modelling of slope stability at the kind of decimetric scale... just a quick example I bashed up today with 3 (!) changed lines of code - a seemingly stable slope (top-left) but which contains a lower-dipping weak interface/fracture .. which is limited in extent - this can be seen by the incremental max. shear strain (top right) at this very early, almost non-visible stage of deformation. Middle panel is when things really "kick off", again incr. max shear strain shown on right. Bottom panel is a more evolved stage, with on the right shown the total displacement magnitude... the resolution here is about 1.4 m, frictional-cohesive materials, scale is shown. Enjoy!
