Experimental Study On Repeatedly Loaded Foundation Soil Strengthened By Wraparound Geosynthetic Reinforcement Technique, Muhammad Nouman Amjad Raja, Sanjay K. Shukla
Experimental Study On Repeatedly Loaded Foundation Soil Strengthened By Wraparound Geosynthetic Reinforcement Technique, Muhammad Nouman Amjad Raja, Sanjay K. Shukla
Research outputs 2014 to 2021
In the recent past, the potential benefits of wraparound geosynthetic reinforcement technique for constructing the reinforced soil foundations have been reported. This paper presents the experimental study on the behaviour of model strip footing resting on sandy soil bed reinforced with geosynthetic in wraparound and planar forms under monotonic and repeated loadings. The geosynthetic layers were laid according to the reinforcement ratio to minimise the scale effect. It is found that for the same amount of reinforcement material, the wraparound reinforced model resulted in less settlement in comparison to planar reinforced models. The efficiency of wraparound reinforced model increased with …

Natural gas trapped in hydrate deposits is a potentially enormous source of energy which can in principle be extracted from the underground reservoir structures. These reserves can potentially also catastrophically release very large quantities of greenhouse gases to the atmosphere. One key parameter which is well known to strongly influence fluid distribution, saturation, and production is rock wettability. However, the effect of wettability on gas hydrate in sediments has not been investigated yet. We thus used nuclear magnetic resonance (NMR) spectrometry to measure relaxation times (T2 and T1) and the corresponding surface relaxivity of tetrahydrofuran hydrate …
Predicting The Settlement Of Geosynthetic-Reinforced Soil Foundations Using Evolutionary Artificial Intelligence Technique, Muhammad Nouman Amjad Raja, Sanjay K. Shukla
Predicting The Settlement Of Geosynthetic-Reinforced Soil Foundations Using Evolutionary Artificial Intelligence Technique, Muhammad Nouman Amjad Raja, Sanjay K. Shukla

In order to ensure safe and sustainable design of geosynthetic-reinforced soil foundation (GRSF), settlement prediction is a challenging task for practising civil/geotechnical engineers. In this paper, a new hybrid technique for predicting the settlement of GRSF has been proposed based on the combination of evolutionary algorithm, that is, grey-wolf optimisation (GWO) and artificial neural network (ANN), abbreviated as ANN-GWO model. For this purpose, the reliable pertinent data were generated through numerical simulations conducted on validated large-scale 3-D finite element model. The predictive power of the model was assessed using various well-established statistical indices, and also validated against several independent scientific …
Influence Of Diagenetic Features On Petrophysical Properties Of Fine-Grained Rocks Of Oligocene Strata In The Lower Indus Basin, Pakistan, Abdul Majeed Shar, Aftab Ahmed Mahesar, Ghazanfer Raza Abbasi, Asad Ali Narejo, Asghar Ali Alias Daahar Hakro

Nari Formation is considered as one of the most important oil and gas exploration targets. These fine-grained tight sandstone reservoirs face enormous challenges due to their extremely low matrix porosity and permeability. Hence, in this regard, the study was carried out to collect the high-quality data on petrophysical properties along with mineralogy and microstructural characteristics and diagenesis. The experiments performed includes the petrographic study and scanning electron microscopy, and X-ray diffraction analyses. Besides, the measurement of petrophysical properties was carried out to assess the likely influence of the reservoir quality. The petrographic analysis shows predominantly fine- to medium-grained grey samples …
