The numerical prediction of vibration in buildings due to underground railways involves modelling many physical phenomena. Not least these is the dynamic soil-structure interaction that exists between various elements system. majority existing models assume railway tunnel and building’s foundation negligible, with two sub-systems behaving as though they are uncoupled. This paper presents some i...

In order to study the deformation of a bored pile during concrete curing, it is necessary monitor strain pile. this paper, Brillouin optical time domain reflectometer (BOTDR) technology used and reliable monitoring data are obtained. These provide basis for pile–soil interaction curing cast-in-place piles. Compared with traditional point sensor, distributed fiber optic sensor simple in layout h...

In this paper, inelastic pile-soil-structure interaction under static loading is presented by using finite element and boundary element methods. Linear beam column finite elements are used to model the piles and structural elements. Nonlinear soil is modeled by using nonlinear springs along the piles. Modified Özdemir’s nonlinear model is implemented for springs and systems of equations are cou...

Shield tunnelling is used widely in constructing underground infrastructure in cities due to the ability to limit settlements and damage to existing buildings. However, in an environment with soft overburden and buildings on pile foundations, the tunnel is often designed well below the pile tip level. There are two reasons for doing this: to reduce interaction between tunnelling process and pil...

Using a series of model tests, this study investigated the effect of a passive pile on 3D ground deformation around a laterally loaded pile and on that laterally loaded pile's response in sand. The active pile head was subjected to lateral loads, and the passive pile was arranged in front of the active pile. In the model tests, the distance between the two pile centers was set to zero (i.e., a ...
