...Ashish Gupta, PhD; Vishwas A. Sawant, PhD Analytical methods to analyse the seismic stability of reinforced soil walls showing the effect of Rayleigh waves are not available to date. In this study, the pseudo-dynamic approach was used to determine the seismic behaviour of a reinforced soil wall...

... to analyse the effect of drainage condition on the dynamic behaviour of Ningbo clay. The results showed that when the cyclic stress ratio (CSR) was small, the accumulated axial strain under undrained conditions was larger than that under partially drained conditions; however, when the CSR was high...

..., incorporation ratios of tyre particles and in corporation ratios of sand, the dynamic shear modulus and damping ratio of the new geomaterial were studied by a torsional shear vibration method based on resonance column tests. The specific control density of steel slag combined with different mixing ratios...

...-induced dynamic elastic stress field in a three-dimensional half-space and introducing a self-equilibrated residual stress field, the maximum magnitude of surface pressure on the soil foundation (i.e. shakedown limit) against long-term residual settlement is calculated through an optimisation programme...

...Amir M. Halabian, PhD, PEng; Arian Shakibzadeh, MSc; Mohammad Ali Rowshan Zamir, PhD The work investigated the effect of using an amino-based resin as a new chemical grout on the static and dynamic behaviour of dry and saturated sands. Several samples of a uniformly graded silty sand having...

...Bashar Tarawneh, PhD, PE; Andrey Sbitnev, PhD; Yasser Hakam, MSc Dynamic replacement (DR) and dynamic compaction (DC) have been used effectively as ground improvement techniques to reduce settlement, increase bearing capacity and mitigate liquefaction. A case study of 11 million m²...

...Sodom Bali Reddy, MTech, PhD; Adapa Murali Krishna, PhD This paper investigates the performance of retaining wall models using recycled tyre chips as compressible inclusions under dynamic loading through shaking table tests. Scrap tyre derived tyre chips of 10 × 10 mm size and about 20 mm length...

... centrifuge testing, small-scale models are subjected to an increased gravitational field that is N times the gravitational acceleration ( g ). The scaling laws were derived for ‘diffusion or static’ events such as consolidation and ‘dynamic’ events such as earthquakes. The time in diffusion events...

...Masoud Hajialilue-Bonab; Fateme Soghra Zare The effect of tamping space and pattern in dynamic compaction has been investigated on loose dry sand using particle image velocimetry technique. A small-scale physical model of dynamic compaction was prepared. Tamping was executed by rising and dropping...

... of an innovative approach for reducing the seismic risk by using soft grouting mixtures installed at an optimum depth in the foundation soil. The basic idea is that a thin grouted layer, with dynamic impedance that is much smaller than that of the surrounding soil, will filter and reflect most of the seismic...

The analysis 4 was conducted for a foundation for a generator which was constructed in Bangalore, India. It was observed...

... by hydraulic filling generally does not allow densification by surface compaction methods because of their limited depth of influence. Loose granular soil is susceptible to liquefaction upon the impact of dynamic forces. Even under static conditions, loose granular soil may be subjected to bearing capacity...
