Remediation of slope failures requires stabilization alternatives that address causes of slope instability. Slope reinforcement and pile stabilization systems, if properly designed, are effective in preventing slope movements in weak soils. Soil load transfer to pile elements from the lateral soil movement as occurs in slope failures is a complex soil-structure interaction problem, and the sign...

A method of damage identification of piles was established by using vibration characteristics. The approach focused on the application of the element strain energy and sensitive modals. A damage identification equation of piles was deduced using the structural vibration equation. The equation contained three major factors: change rate of element modal strain energy, damage factor of pile, and s...

Many offshore structures are subjected to overturning moments due to wind load, wave pressure, and ship impacts. Also most of retaining walls are subjected to horizontal forces and bending moments, these forces are due to earth pressure. For foundations in such structures, usually a combination of vertical and batter piles is used. Little information is available in the literature about estimat...

Many spatial patterns observed in nature emerge from local processes and their interactions with the local environment. The clustering of objects by social insects represents such a pattern formation process that can be observed at both the individual and the collective level. In this paper, we study the interaction between air currents and clustering behaviour in order to address the coordinat...

We present numerical experiments investigating the shape and spin limits of self-gravitating “perfect” rubble piles that consist of identical, smooth, rigid, spherical particles with configurable normal coefficient of restitution and no sliding friction. Such constructs are currently employed in a variety of investigations, ranging from the formation of asteroid satellites to the dynamical prop...

[1] Heterogeneous compositional mantle models are frequently invoked to explain some observations obtained from geochemistry and seismology. In particular, two regions in the Earth’s lower mantle, under the Pacific and Africa, are often interpreted as being either piles or superplumes of dense material. We perform numerical modeling of thermochemical convection in a three-dimensional spherical ...

Understanding the role that facultative scavenger species may play in spreading infectious pathogens, and even becoming reservoirs for humans, domestic and wild ungulates or, on the contrary, preventing the spread of disease, requires a prior understanding of the pattern of carrion scavenging in specific scenarios. The objectives of this paper are (i) to describe the guild of vertebrate scaveng...

so far, for an analysis of seepage under hydraulic structures much research has beenconducted in the form of numerical models. however, few field and laboratory workshave been performed to study the boiling phenomena for evaluating numerical models.throughout the present work, a laboratory model was built to simulate seepage and itscontrolling measures under sheet piles. the model consisted of ...

PARTIAL-MOMENT-CONNECTION TO THE DECK IN MARINE OIL TERMINALS By Rakesh K. Goel, F.ASCE ABSTRACT This paper presents development of a simplified procedure for seismic evaluation of piles with partial-moment-connection typically used in marine oil terminals. The current seismic evaluation procedure of the piles in marine oil terminals includes monitoring material strains specified in the Marine ...
