A probabilistic deep reinforcement learning approach for optimal monitoring of a building adjacent to deep excavation

Comput. Aided Civ. Infrastructure Eng., 2023
During a deep excavation project, monitoring the structural health of the adjacent buildings is crucial to ensure safety. Therefore, this study proposes a novel probabilistic deep reinforcement learning (PDRL) framework to optimize the monitoring plan to

Simplified method for evaluating the response of existing tunnel induced by adjacent excavation

International journal for numerical and analytical methods in geomechanics (Print), 2022
Adjacent excavation may have a negative influence on the existing tunnel underneath. Thus, it is important to evaluate the response of the tunnel due to adjacent excavation.

Excavating Knowledge

2023
Conversations about heritage and democracy point to the significance and role of archaeology in education. Drawing on critical education pedagogies, together with politically engaged archaeological work, this chapter examines Excavating Knowledge, a community engaged heritage and education project that is part of ongoing archaeological work at ...

Behaviour of existing tunnel due to adjacent deep excavation - a review

International Journal of Geotechnical Engineering, 2021
Behaviour of existing tunnel gets hugely affected by nearby construction activities, especially from deep excavation, which causes changes in the ground stresses.

Stepwise Excavation

2018
The most recent inspiration for stepwise carious tissue removal in 2 stages originates from the knowhow on intralesion changes in deep carious lesions. The environmental change that takes place during the first stage of carious tissue removal is aiming for the arrest of the deep lesion, by placing a temporary restoration on top of the soft carious ...

Evaluation of excavation-induced movements through case histories in Hangzhou

, 2020
Deep excavation in soft clay often causes additional deformations to surroundings. Then, if deformations cannot be predicted reasonably, the adjacent buildings may be threatened by the deep excavation.
