Simulating Dynamical Features of Escape Panic [PDF]

, 2000
One of the most disastrous forms of collective human behaviour is the kind of crowd stampede induced by panic, often leading to fatalities as people are crushed or trampled.

Effects of Artificial Texture Insoles and Foot Arches on Improving Arch Collapse in Flat Feet [PDF]

Sensors, 2020
The arches of the foot play a vital role in cushioning the impact and pressure generated from ground reaction forces due to body weight. Owing to a lack of normal human arch structure, people diagnosed as having flat feet often have discomfort in the soles of their feet.

Analysis of influencing factors on the soil arching effect of anti-slide piles in reservoir bank landslides

Frontiers in Earth Science
Anti-slide piles are widely used for landslide mitigation, providing an effective engineering solution for slope protection. A critical factor in the design and performance of these structures is the soil arching effect, which arises from the interaction

A calculation method of earth pressure on sheeting between two piles considering soil arching effect and intermediate principal stress

Shuiwen dizhi gongcheng dizhi, 2022
The classical theories of earth pressure are based on the M-C strength criterion, which do not consider the influence of soil arching effect and intermediate principal stress on earth pressure, so the theoretical earth pressures are significantly larger ...

Effect of Equivalent Load Distribution on the Accuracy of Mapping the Reinforcement Load Deflection Curve in LTP

Applied Sciences, 2020
The formulations of tasks modelling embankments on soft soil, improved with columns and with reinforced load transfer platform (LTP), differ significantly. One of these differences is the distribution of equivalent load modelling part of the load carried

Experimental and numerical study on the soil arching effect caused by deep-buried shield tunneling

Underground Space
The soil arching effect induced by deep-buried shield tunneling strongly influenced the ground stress and displacement. Therefore, revealing the evolution mechanism of the soil arching effect is a prerequisite for accurately predicting the tunnel load ...

High intensity tapping regime in a frustrated lattice gas model of granular compaction

, 2010
In the frame of a well established lattice gas model for granular compaction, we investigate the high intensity tapping regime where a pile expands significantly during external excitation.
