Dynamic response of driven end-bearing piles and a pile group in soft clay: an experimental validation study
نویسندگان
چکیده
This paper presents novel measurement data on the dynamic soil–structure interaction of an end-bearing pile foundation. The purpose is to assess ability predict foundation impedances based small-strain properties soil obtained from site investigations. Measurements were performed in two stages construction, allowing between piles through soil. First, single and factors experimentally for four when they free move at surface. Second, square group measured after casting a concrete cap. additionally instrumented with accelerometers depth along centerline each pile, illustrate global behaviour within Numerical predictions solely information extensive investigations are compared experimental results. individual overestimated measurements, while show better agreement. captured than ones, using same model. pile–soil–pile clearly manifested results by pronounced peaks vertical impedance, validating previous numerical studies.

Seismic response of end-bearing single piles
A numerical study is presented of the dynamic response of end-bearing piles embedded in a number of idealized soil deposits and subjected to vertically propagating harmonic S-waves. Results, for both 'kinematic' and 'inertial' interaction, are offered in the form of dimensionless graphs and formulae covering a wide range of excitation frequencies and of crucial material and geometric parameters...
متن کاملEvaluation of Static and Dynamic Methods for Determining the Bearing Capacity of the Driven Pipe Piles (TECHNICAL NOTE)
Determination of the pile capacity is always a major concern for the safe geotechnical engineering design. Different direct and indirect methods have been proposed for determining pile bearing capacity such as static and dynamic approaches. Each method depends on the condition of the soil and type of pile as well as accessibility to necessary information. In this study bearing capacity of drive...

a contrastive study of rhetorical functions of citation in iranian and international elt scopus journals
writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
