Influences of Railway Track Geometry Parameters on Ground-Borne Vibration

One of the most important challenges in the development of urban railways network is the effects of railway vibrations on human and adjacent structures. Although various investigations into the sources of railway vibrations have been conducted, very few research works have been reported on the influences of track geometry parameters on the level of vibrations. This is addressed in this resea...

Effect of Ground Subsidence on Load Sharing and Settlement of Raft and Piled Raft Foundations

In this paper, two centrifugal model tests (case 1: raft foundation, case 2: 2x2 piled raft foundation) were conducted in order to evaluate the effect of ground subsidence on load sharing among piles and raft and settlement of raft and piled raft foundations. For each case, two conditions consisting of undrained (without groundwater pumping) and drained (with groundwater pumping) conditions wer...

Load transfer on single pile near new tunneling in sandy ground

S: A series of centrifuge model tests were performed to assess the tunneling-induced ground deformations and their detrimental effects on the neighboring single pile in the saturated sandy ground. The relative elevations between the pile tip and the buried depth of new driven tunnel dominated the distributions of bending moment and axial force along the depths. A load transfer mechanism is prop...

Effect of Passive Pile on 3D Ground Deformation and on Active Pile Response

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 ...
