In order to understand the deformation law and internal force distribution characteristics of pile-anchor retaining structure in deep foundation pit engineering, stress system process excavation was tested by using distributed optical fiber sensing technology BOTDA. It uses supporting pile cloth set up strain cable collect from stability pit, which analyzes distribution. The results show that o...

Aiming at the problem of insufficient research on action mechanism and stability calculation method top beam in pile-anchor support structure, firstly force deformation model are established based elastic fulcrum coordination principle structure pile anchor end this paper. Secondly, under synergy crown simplified internal force, displacement overall slope constructed. Finally, combined with an ...

Suction caisson is a type of floor foundation for the offshore structures that is also called suction pile, bucket foundation, suction anchor, or sometimes ridge foundation depending on its application. In two past decades, this type of foundation has been widely used around the world as the fixed offshore foundation, anchor of the floating platforms, as well as the foundation of other marine s...

Granular materials are predominantly plastic, incrementally nonlinear, preparation-dependent, and anisotropic under shear. Nevertheless, their static stress distribution is well accounted for, in the whole range up to the point of failure, by a judiciously tailored isotropic nonanalytic elasticity theory termed granular elasticity. The first purpose of this paper is to carefully expound this vi...

Anyone who has built a sandcastle recognizes that the addition of liquid to granular materials increases their stability. However, measurements of this increased stability often conflict with theory and with each other [1–7]. A friction-based Mohr-Coulomb model has been developed [3, 8]. However, it distinguishes between granular friction and inter-particle friction, and uses the former without...

We investigate the dynamics of regolith on rubble-pile asteroids to explain granular processes observed in reality. In particular, we how appearance boulders surface asteroid Itokawa could have resulted from a size sorting process media called Brazil Nut Effect (BNE). The Discrete Element Method (DEM) is implemented perform numerical simulations BNE micro-gravity environment caused by inter-par...

– In a seminal experiment, Jaeger et al. (Phys. Rev. Lett., 62 (1989) 40) measured the power spectrum of the velocity of avalanches along a granular pile in a rotating drum. Although their findings started an actively discussed debate on whether self-organized criticality rules granular avalanche dynamics, their experimental results have not been explained in theoretical detail yet. By the use ...

In Chile, for the design of an excavation support system, recommendations NCh3206 standard are used, which its update is being processed. Both current and update, alternative uniform or trapezoidal earth pressure distribution a retaining wall with one anchor level mentioned. For standard, it indicated that analysis should be performed both distributions must used most unfavorable other can used...
