Soil-structure Interface Modelling: Influence of Impregnation
نویسنده
چکیده
Information on the influence of impregnation of cementitious slurry at the soil-structure interface of bored cast in-situ foundation is inadequate in available literatures. Moreover, influence of such impregnation on negating the detrimental effects of smear zone, formed by construction tools, surrounding the borehole is also unknown. In classical foundation engineering, influences of smear and impregnation are neither considered as dependent functions in determining contributory or negative shaft resistances, nor in shaft and base resistance interaction. This ignorance contributes empiricism in bearing capacity evaluation recognising it as one of the possible causes of variation of field performance with respect to prediction. Solution to these problems has been explored through field and simulated laboratory studies of smear and impregnation, developing new device and technique. Further, an approach to interface modelling of soil-structure is presented considering impregnation.

Numerical and Experimental Study of Soil-structure Interaction in Structures Resting on Loose Soil Using Laminar Shear Box
In the present work, the effect of Soil-Structure Interaction (SSI) in low frequency structures resting on loose soil, through numerical modelling and shaking table tests have been studied. In theoretical studies two types of models namely fixed base and flexible base structure were subjected to three selected earthquake records. Nonlinear dynamic analysis was employed for all of the numerical ...
متن کاملBoundary Element Analysis of a Lined Tunnel Problem
The boundary element technique is a practical problem-solving tool and useful in comparison to other currently popular alternatives. In this paper, a circular tunnel of a diameter 3.4 m is to be excavated through a clayey soil and surrounded by concrete lining of a thickness 0.2 m, so the clear internal diameter is 3.0 m. A plane strain analysis is adopted for such problem and the soil is assum...
متن کاملA numerical analysis of effect of segmental lining joints on tunnel support internal forces under seismic loading
During an earthquake, the better performance of segmental tunnel lining, compared to the continuous in-cast concrete lining, is generally related to the joints between segments. In order to better understand the influence of the segment joints, their effect on the internal forces induced in tunnel lining simultaneously with the effects of the other influential parameters should be considered. I...
متن کاملInfluence of the Imperfect Interface on Love-Type Mechanical Wave in a FGPM Layer
In this study, we consider the propagation of the Love-type wave in piezoelectric gradient covering layer on an elastic half-space having an imperfect interface between them. Dispersion relation has been obtained in the form of determinant for both electrically open and short cases. The effects of different material gradient coefficients of functionally graded piezoelectric material (FGPM) and ...
متن کاملHigh‐resolution synchrotron imaging shows that root hairs influence rhizosphere soil structure formation
In this paper, we provide direct evidence of the importance of root hairs on pore structure development at the root-soil interface during the early stage of crop establishment. This was achieved by use of high-resolution (c. 5 μm) synchrotron radiation computed tomography (SRCT) to visualise both the structure of root hairs and the soil pore structure in plant-soil microcosms. Two contrasting g...
