DOI: 10.1016/j.tust.2021.104046
Abstract: Abstract Conventional deep excavation support systems (diaphragm wall with inner strut) have fixed length of struts, which can lead to a significant discrepancy between deformations of actual and designed diaphragm wall systems. As a result,… read more here.

DOI: 10.1080/19386362.2021.1952800
Abstract: Behaviour of existing tunnel gets hugely affected by nearby construction activities, especially from deep excavation, which causes changes in the ground stresses. Such change in stress will affect ... read more here.

DOI: 10.18690/actageotechslov.18.1.2-14.2021
Abstract: Deep excavations in urban areas impose deformation to adjacent structures; hence the reliability of deformation analysis for the real deep excavation projects is very important to be assessed. In this study a framework is presented… read more here.
