The study of patterns crowd flows represents an emerging and expanding research field. most straightforward efficient approach to investigate the is concentrate on traffic flow. However, assessments simple point-to-point movement frequently lack universal validity, little has been conducted regularity nighttime movement. Due suspension public transportation at night, taxi orders are critical in...

Designing and building structures infrastructures with alternative environmentally friendly materials is, nowadays, an important step towards a more sustainable society. Recycled Construction Demolition (C&D) have been considered as in different civil engineering applications, such unbound pavement layers structural embankments, which geosynthetics are also frequently applied. If the durability...

As a new type of reinforced material, geocells are widely used in flexible retaining wall projects, and lot practical experience shows that the geocell has great effect on earthquake resistance, but theoretical research lags behind engineering practice, deformation failure mechanism under need to be further studied. In this paper, we use FLAC3D nonlinear, finite-difference method study geocell-...

This study was conducted to investigate the potential benefits of using geogrids in mitigating pavement defects notably roughness and longitudinal cracking on pavements built over expansive soils. The seasonal changes soils (periodic wetting drying) cause detrimental effects overlying road pavements. Such behavior simulated a controlled laboratory environment through allowing cyclic drying an s...

Geosynthetics are widely used in earth retaining structures such as steep slope and wall. The stability of the depends on interaction between geosynthetics soil at reinforced area known reinforcement mechanism. mechanism structure usually difficult to be analysed thoroughly. It is because preliminary study pull-out resistance durability material not taking into account before it has been site l...

Abstract The experimental work of this study deals with the performance pipe in sand various responses subjected to incremental static loading where backfill is reinforced two types reinforcement (geogrid and geocell) investigate effects cover. pipes considered are installed different densities; i.e., loose, medium dense sand, a constant burial depth (2D, D diameter). It was concluded that maxi...

This paper presents the results of a series of small-scale model tests and numerical analyses conducted on circular and ring model footings located near geogrid reinforced sand slopes. Layers of geogrid were used as reinforcement. For numerical analyses Finite Element Method (FEM) was used. The effects of reinforcement depth, size, number of layers, and the horizontal distance between reinforce...
