The analysis of landslide slope stability since 1960s is the development a 2-D structure proposed by various experts, through 3-D method. Most these previous studies stated that ratio and safety factors was more than one for cohesive less non-cohesive soils. These were because several required reinforcements affected factors, with analytical differences methods causing distinction in requiremen...

This research investigated the effects of types cohesive-frictional soil and geotextile reinforcement configurations on bearing capacity reinforced foundation (RSF) structures, via laboratory test numerical simulation. The four studied for RSF included: (i) horizontal planar form geotextile, (ii) full-wraparound ends (iii) with filled-in sand, (iv) sand backfill. soils were mixtures fine sodium...

The main purpose of our project is to test the improvement in CALIFORNIA BEARIBG RATIO SUBGRADE SOIL upon usage GEOTEXTILE layer soil. We planned effect geotextile under different conditions placement height, soil characterstics and moisture content. performed experiments laboratory determine results variation CBR value plotted it draw inferences. Key Words: CBR, Geotextile, Subgrade, Moisture ...

Geotextiles incorporating inorganic nutrients (particularly phosphorous) to enhance the growth of oil degrading microoganisms when geotextiles are used in pervious pavement applications have been shown to be effective in the past. However the cost and manufacturing difficulties have been a barrier to their use. A polypropylene random mat geotextile incorporating an alternative polymer additive ...

Abstract One of the methods of increasing soil resistance against failure is soil reinforcement using geosynthetics. Soil-geosynthetic interactions are of great importance and are affected by friction and adhesion at their interface. Soil gradation, contact surface roughness and geotextile density are among the factors affecting soil-geotextiles interaction this study, to investigate the eff...

The presence of underground voids within a failure zone usually results in reduction the bearing capacity footings. This paper presents for ultimate ratio, qu/γB, strip footing on top sand layer overlying clay with voids, and without placing geotextile reinforcement at interface between layers. Using finite difference software FLAC 2D, ratio was calculated different depths horizontal distance t...

This article reports the development and construction of a 1:1 scale laboratory prototype of a System for Catchment, Pre-treatment and Treatment (SCPT) of runoff polluted by contaminants washed from impervious pavements. The concept of the SCPT is an online system with an up-flow filter. The filter is composed of geotextile layers and limestone. The laboratory tests carried out were focused on ...

The installation procedures (which induce mechanical damage) and abrasion can cause unwanted changes on the properties of the geotextiles. In this work, a nonwoven polypropylene geotextile was subjected to three degradation tests: (1) mechanical damage, (2) abrasion and (3) mechanical damage followed by abrasion (successive exposure). The damage caused by the degradation tests was evaluated by ...
