Abstract Colloidal silica (CS) grouting is a soil improvement technique introduced as an innovative remedial measure against seismic liquefaction. It consists of injecting soils with time-hardening, nanosilica-based solution forming gel among particles. This paper presents the results experimental study on effects initial static shear stress behaviour cyclically loaded clean sand stabilised 5% ...

In this study artificial neural networks (ANN) are used to simulate the monotonic and cyclic behaviour of sands observed in laboratory tests on Karlsruhe sand under drained undrained conditions. A genetic algorithm (GA) is obtain an optimal framework for ANN. The results show that proposed adaptive network (GANN) can effectively triaxial saturated isotropic or anisotropic consolidation. GANN al...

In the present paper, the Zelt algorithm has been extended for ray tracing through an anisotropic model. In anisotropic media, the direction of the propagated energy generally differs from that of the plane-wave propagation. This makes velocity values to be varied in different directions. Therefore, velocity modeling in such media is completely different from that in an isotropic media. The vel...

formability of automotive friction stir welded twb (tailor welded blank) sheets isnumerically investigated in biaxial stretching based on hemispherical dome stretch (hds) test infour automotive sheets of aluminum alloy 6111-t4, 5083-h18, 5083-o and dp590 steel, havingdifferent thicknesses. the effects of the weld zone modeling and the thickness ratio on formabilityare evaluated. in order to car...

Pore pressure evolution induced by tunnel excavation in low permeability anisotropic ground is investigated means of a fully coupled hydro-mechanical finite element simulation. The goal to explore the main trends pore on basis poroelastic analysis, taking into account: one hand, influence and face advance; other inherent anisotropy material. It shown that overpressures can be before passage fac...

geotechnical investigations of waste fills are rarely undertaken, and consequently the geotechnical community has little knowledge of their engineering properties. in this study, a geotechnical testing program was conducted to evaluate the engineering properties of old municipal solid waste sampled in whamyung msw landfill site, busan, korea. the conducted tests included water content, specific...

Vertical drains and stone columns which have been used in infrastructure construction for highways, ports, coastal regions, etc., provide significant benefits for improving soil characteristics such as reducing the drainage length and accelerating the consolidation process. So the investigation of the radial consolidation is inevitable. Soils may be subjected to cyclic loading such as silos, ta...
