The mechanical behaviour of unsaturated soils is one of the challenging topics in the field of geotechnical engineering. The use of finite element technique is considered as a promising method to solve settlement and heave problems, as associated with unsaturated soil. Nevertheless, the success of the numerical analysis is strongly dependent on constitutive model being used. The well-known Barc...

Studying the stability of slopes is great interest since it associated to various geotechnical applications, e.g., access embankments and landslide mitigation. This paper describes research conducted determine failure load applied at top excavations in sandy soils during construction deep digs without use retaining systems. An experimental program was performed measure ten laboratory-compacted ...

A jack-up structure is a bottom-mounted floating unit having an adjustable hull and movable legs. Particular structures are more susceptible to hazards under environmental loads during their operation life cycle in the ocean. Authors' attempts here enhance its sustainability shallow deep waters by correctly accessing soil behaviour predicting load carrying capacity. Here numerical analysis of s...

Abstract The composite system of stone columns reinforced soil overlaid by granular mattress (GM) has been given more attention as a hybrid improvement technique. This work presents 3D finite element analyses using PLAXIS software for floating group constructed in deep soft clay deposit Port-Said Egypt. limited area loading was investigated conjunction with the key parameters, i.e., length, dia...

This study used a finite element analysis approach employing Plaxis 3D to analyze the stress concentration ratio, critical parameter in geotechnical engineering, examine stresses operating on stone columns and soft soils. also looked at effect of stiffness ratio between column neighboring soil. With same length three different diameters, 0.8 m, 1.0 1.2 or area replacement ratios ranging from 7%...

Abstract Model study was carried out in the laboratory to know effect of uplift loads on vertical piles, batter piles and pile groups. Mild steel having 22 mm outer diameter 1 thickness were considered for study. Different slenderness ratios 18, 28, 38 various angles such as 0°, 15°, 25°, 35°, 45° Sand poured at a fixed relative density mild tank. The experimental shows that group attain maximu...

In a combined piled raft foundation (CPRF) both and piles take their share of the total load applied. However, in practice, contribution taking is usually ignored assumed to be supported on piles. This way CPRF becomes excessively conservative uneconomical. To economize design, relative sharing has found. this connection, different simplified methods have been developed, each one with some limi...
