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: 10.3390/sym14071462
Abstract: An analytical formulation involving residual force is proposed to predict the displacement of an existing structure by simplifying the tunnel as an infinite Euler–Bernoulli beam resting on a two-parameter Pasternak foundation. The feasibility is confirmed… read more here.
